Nielsen tracks the amount of time that people spend consuming media content across different platforms (digital, audio, television) in the United States. Nielsen has found that traditional television viewing habits vary based on the age of the consumer as an increasing number of people consume media through streaming devices (Nielsen website). The following data represent the weekly traditional TV viewing hours in for a sample of people aged and people aged .
Viewers aged 18–34 24.2 21.0 17.8 19.6 23.4 19.1 14.6 27.1 19.2 18.3
22.9 23.4 17.3 20.5
Viewers aged 35–49 24.9 34.9 35.8 31.9 35.4 29.9 30.9 36.7 36.2 33.8
29.5 30.8
Required:
a. Compute the mean and median weekly hours of traditional TV viewed by those aged 18–34.
b. Compute the mean and median weekly hours of traditional TV viewed by those aged 35–49.
c. Compare the mean and median viewing hours for each age group. Which group watches more traditional TV per week?
Answer:
Step-by-step explanation:
a) Mean = sum of variables/sample size
For Viewers aged 18-34
Data given
24.2 21.0 17.8 19.6 23.4 19.1 14.6 27.1 19.2 18.3
22.9 23.4 17.3 20.5
Sum of variables = 34+24.2+21.0+17.8+19.6+23.4+19.1+14.6+27.1+19.2+18.3 +22.9+23.4+17.3+20.5
= 288.4
Sample size = 14
Mean = 288.4/14
Mean = 20.6
Median is the value at the middle of the data after rearranging either ascending or descending order.
On re arranging
14.6, 17.3, 17.8, 18.3, 19.1, 19.2, )19.6, 20.5, (21.0, 22.9, 23.4, 23.4, 24.2, 27.1
Based on the arrangement it can be seen that the value at the middle is 20.5 and 19.6 so we will take the average of the values.
Median = 19.6+20.5/2
Median = 20.05
hence the median value is 20.05
b) For Viewers aged 35-49
Data given
24.9 34.9 35.8 31.9 35.4 29.9 30.9 36.7 36.2 33.8
29.5 30.8
Sum of variables = 24.9+34.9+35.8+31.9+35.4+29.9+30.9+36.7+36.2+33.8 +29.5+30.8
= 390.7
Sample size = 12
Mean = 390.7/12
Mean = 32.56
Median is the value at the middle of the data after rearranging either ascending or descending order.
On re arranging
24.9, 29.5, 29.9, 30.8, 30.9), 31.9, 33.8, (34.9, 35.4, 35.8, 36.2, 36.7
Based on the arrangement it can be seen that the value at the middle is 31.9 and 33.8. Taking the average vale;
Median = 31.9+33.8/2
median = 32.85
Hence the median of the data is 32.85
c) Based on both means, the mean value of the people between ages 35-49 is grater than that of ages 18-34. This shows that the people under age of 35-49 watches more traditional TV per week and due is due to the greater mean value they possess.
The median value of the people between ages 35-49 is also grater than that of 18-34 by 12.8 (32.85-20.05)
Katrina, Jackie, and Molly are making crafts for the craft fair. Katrina has 3/10
made of hers, Jackie has made 2/5 of hers, and Molly has made 1/2 of
hers. Which shows these amounts in order from SMALLEST to LARGEST?
Answer:
Step-by-step explanation:
First you need to find a common denominator which in this case it 10
*Remember that whatever you do to thee bottom you need to do to the top*
3/10 - 3/10
2/5 = 4/10
1/2= 5/10
So the order is
Katrina - 3/10
Jackie - 4/10
Molly - 5/10

Answer:
(-5,2); opens up
Step-by-step explanation:
In the equation y = a(x − h)² + k, if a is positive it opens up
The vertex is: (h, k)
Since in the equation h is multiplied by a negative one, you have to flip the sign of h in the equation.
(x-(-5)) = (x+5)
Name a linear pair of angles must be 2 pairs. Image included.
Answer:
Pair 1 and 2, pair 2 and 3, pair 3 and 4, pair 4 and 1
Step-by-step explanation:
Any pair of numbers that isn't diagonal from each other can be a pair. A linear pair is simply two angles that add up to 180°, so if you have a completely straight line with a ray coming up from it at any angle, that's a linear pair. Choose any two of the four options I gave you.

Answer:
In one Pb&j it is 385 and in three it has 1,155 (385×3=1,155 )
Answer:
part A = x= 385 Part B= Part A Part C= 1155
Step-by-step explanation:
Part A
770/2 = x/1
770= 2x
x= 385
Part B
Thats the same question as part A? so just use the answer from A i guess
Part C
770/2 = x/3
2310 = 2x
x = 1155

algebra one question
Consider the experiment of tossing a coin twice.
a. List the experimental outcomes. (Let H represent a coin landing on heads and T represent a coin landing on tails.)
b. Let denote the number of heads occurring on two coin tosses. Show what value the random variable would assume for each of the experimental outcomes.
c. Define a random variable that represents the number of heads occurring on the two tosses.
d. Is this random variable discrete or continuous?
Answer:
Kindly check explanation
Step-by-step explanation:
Experiment of tossing a coin twice :
A.) Experimental outcome:
Head = H ; Tail = T ;
Head and Head = HH
Tail and Tail = TT
Head and Tail = HT
Tail and Head = TH
Number of head(s) on toss = z
C)
Experimental outcome ___number of heads(z)
HH _____________________2
TT _____________________ 0
TH _____________________ 1
HT _____________________ 1
D) the random variables defined are discrete because they are only take up integer values within a specified range
The following conclusions of the random variable will be
a. Total outcome = 4 {HH, HT, TH, TT}
b. The experimental outcomes = 2 {TH, HH}
c. The experimental outcomes = 1 {HH}
d. Random variable is discrete.
What are random variables?Random variables are rules relating the sample space's elements to real numbers.
What are discrete random variables?Those random variables, which take only distinct values, are called discrete random variables.
What are continuous random variables?Those random variables, which take any value from a given continuous interval of real numbers are called continuous variables.
The experiment of tossing a coin twice.
The total number of outcomes will be
Total outcome = 4 {HH, HT, TH, TT}
a. List the experimental outcomes.
Total outcome = 4 {HH, HT, TH, TT}
b. The number of heads occurring on two coin tosses.
The experimental outcomes = 2 {TH, HH}
c. A random variable that represents the number of heads occurring on the two tosses.
The experimental outcomes = 1 {HH}
d. Random variable is discrete.

Zoe bought 1.5 pounds of apples for $3.50 per pound. She wanted to find the total cost using partial products.
Answer:
She spent $5.25
Step-by-step explanation:
The total cost of the apples is $5.25 if Zoe bought 1.5 pounds of apples for $3.50 per pound.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Zoe bought 1.5 pounds of apples for $3.50 per pound.
Let x be the total cost of the product:
x = 3.50x1.5
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
x = $5.25
Thus, the total cost of the apples is $5.25 if Zoe bought 1.5 pounds of apples for $3.50 per pound.

A recently admitted class of graduate students at a large state university has a mean GRE verbal score of 650 with a standard deviation of 50. The scores are reasonably normally distributed. Five students have parents who happen to be on the board of trustees, and these students were admitted with a mean GRE score of 490. Should the local newspaper editor write a scathing editorial about favoritism?
Answer:
The answer is below
Step-by-step explanation:
The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:
[tex]z=\frac{x-\mu}{\sigma} \\\\\mu=mean, \sigma=standard\ deviation,x=raw\ score\\\\for\ a\ sample\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }[/tex]
Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{490-650}{50/\sqrt{5} } =-7.16[/tex]
From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%
Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism
Find the solution to the following system using substitution or elimination: y = 3x + 2 y = -2x - 8 O A. (-5,-) OB. (-2,-4) O C. (1,-6) O D. (-:-)
Answer:
B. (-2,-4)
Explanation
Given equations:
y = 3x + 2
y = -2x - 8
Solving both equations will yield the values of x and y;
Solution:
y = 3x + 2 ----- (i)
y = -2x - 8 ------ (ii)
Using substitution method, input equation i, into ii
3x + 2 = -2x - 8
Collect like terms and solve;
3x + 2x = -8 -2
5x = -10
x = -2
Then put x = -2 into i, to find y
y = (-2 x 3) + 2
y = -6 + 2 = -4
So, the solution of the equation is B. (-2,-4)
