Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $30,000 and $50,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. Given the information in the Microsoft Excel Online file below, construct a spreadsheet to determine how large a sample should be taken for each desired margin of error.
Answers
Answer:
A. 384.16
B. 2,401
C. 9,604
D. No
Step-by-step explanation:
Calculation to determine how large a sample should be taken for each desired margin of error
First step is to find σ which represent Population Standard deviation
σ=($50,000-$30,000)/4
σ=$20,000/4
σ = 5,000
Now let calculate how large a sample should be taken for each desired margin of error
Using this formula
n = (Za/2*σ/E)^2
Where,
Za/2=1-0.95/2
Za/2=0.05/2
Za/2=0.025
Z-score 0.025=1.96
Za/2=1.96
σ =5,000
E represent Desired margin of error
Let plug in the formula
a. $500
n = (1.96* 5,000/$500)^2
n=(9,800/$500)^2
n=(19.6)^2
n = 384.16
b. $200
n = (1.96*5,000/200)^2
n=(9,800/$200)^2
n=(49)^2
n = 2,401
c. $100
n = (1.96*5,000/$100)^2
n=(9,800/$100)^2
n=(98)^2
n = 9,604
Therefore how large a sample should be taken for each desired margin of error will be :
A. $500= 384.16
B. $200= 2,401
C. $100= 9,604
d.NO, Based on the information calculation i would NOT recommend trying to obtain the $100 margin of error reason been that it is highly costly compare to $500 margin of error and $200 margin of error.
a chord subtends an angle of 34 at the center of a circle of radius 4cm find the length of the chord (take =22/7)
Answers
Answer:
2.34 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle at the centre (θ) = 34°
Radius (r) = 4 cm
Length of chord (C) =?
The length of the chord can be obtained as follow:
C = 2rSine(θ/2)
C = 2 × 4 × Sine(34/2)
C = 8 × Sine 17
C = 8 × 0.2924
C = 2.34 cm
Therefore, the lenght of the chord is 2.34 cm.
For the following compound interest problem, how much interest would you earn if you put $600 in the bank at 5.5% for 2.25 year.
Answers
Answer:
$74.25
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
then, solving our equation
I = 600 × 0.055 × 2.25 = 74.25
I = $ 74.25
The simple interest accumulated
on a principal of $ 600.00
at a rate of 5.5% per year
for 2.25 years is $ 74.25.

How much did they pay
Answers
Answer:
The answer is B
Step-by-step explanation:
I know the answer is $102.20 because since there are 15 members in total I would suggest that you would subtarct by 8 and you would get 7 . Beacuse 8 out of the 15 memebers already payed the first day
So that means 7 memebers have to pay each member has to pay 14.60...
That means 7 memeber times $14.60 will equal $102.20\
Hope this helps!!
Answer:
B. $102.2
Step-by-step explanation:
You will subtract the 8 members who payed their dues on the first day of the month, getting 7 members left to pay their dues. Then you will multiply 7 • $14.60 = $102.2 payed the second day of the month.

Find the degree measure of each angle in the triangle.
Answers
Answer:
m<I=57
m<J=57
m<K=66
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
m<I= 3x+18
m<K= 5x+1
m<I is congruent to m<J.
We can plug the information we already know into the equation.
3x+18+3x+18+5x+1=180
11x+37=180
Subtract 37 from both sides.
11x=143
x=13
Now, we can find out what the angles are.
m<I= 3x+18
m<I=3(13)+18
m<I=39+18
m<I=57
We know that m<I=m<J, so they are both equal to 57 degrees.
m<J=57
Now for m<K:
m<K=5x+1
m<K=5(13)+1
m<K=65+1
m<K=66
We know this is correct because 57+57+66=180.

Answers
Answer:
square, parallelogram, rectangle, rhombus
Step-by-step explanation:
Considering the answer choices:
Square
Regular pentagon
Parallelogram
Rectangle
Rhombus
It can't be a pentagon because it only has four sides.
Properties of the shapes:
Rectangle - quadrilateral with two sets of congruent opposite sides and four right angles.
Rhombus - quadrilateral with four congruent sides.
Square - quadrilaterals with all properties of rectangles and rhombi.
Parallelogram - rectangles, rhombi, and squares are parallelograms.
This shape satisfies the properties of a square, meaning it is also a rectangle, rhombus, and parallelogram.
Ally collects stickers as a hobby. She gives her sisters of her stickers.
She then gives her cousin of the remainder.
Ally says that she has 3/5 of the stickers in the end because 1-1/5-1/5=3/5
• Explain why Ally's reasoning is incorrect.
What should the correct answer be?
Explain how you arrived at your answer.
Answers
Answer:
[tex]\frac{16}{25}[/tex]
Step-by-step explanation:
Ally gives her sister = 1/5 stickers
Ally gives her cousin = 1/5 of the remainder stickers
Assume Number of sticker Ali has = 1
Remainder after giving stickers to her sister = 1 - 1/5 = 4/5
Number of stickers she gave her sister = [tex]\frac{1}{5}\times\frac{4}{5}[/tex]
=[tex]\frac{4}{25}[/tex]
Sticker she has = [tex]1-\frac{1}{5}-\frac{4}{25}[/tex]
=[tex]\frac{25-5-4}{25}[/tex]
=[tex]\frac{16}{25}[/tex]
Sticker left with Ally is equal to [tex]\frac{16}{25}[/tex].
