According to Inc, 79% of job seekers used social media in their job search in 2018. Many believe this number is inflated by the proportion of 22- to 30-year-old job seekers who use social media in their job search. Suppose a survey of 22- to 30-year-old job seekers showed that 308 of the 370 respondents use social media in their job search. In addition, 281 of the 370 respondents indicated they have electronically submitted a resume to an employer.
A) Conduct a hypothesis test to determine if the results of the survey justify concluding the proportion of 22- to 30-year-old job seekers who use social media in their job search exceeds the proportion of the population that use social media in their job search. Use α = 0.05.
1) State the null and alternative hypothesis.
2) Find the value of the test statistic.
3) Find the p-value.
B) Conduct a hypothesis test to determine if the results of the survey justify concluding that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer. Using α = 0.05, what is your conclusion?
1) State the null and alternative hypothesis.
2) Find the value of the test statistic.
3) Find the p-value.
Answer:
A) i) Null hypothesis; p ≤ 0.79
Alternative hypothesis; p > 0.79
ii) test statistic = 2
iii) P-value = 0.02275
B) i) Null hypothesis; p ≤ 0.70
Alternative hypothesis; p > 0.70
ii) test statistic = 2.5
iii) P-value = 0.00621
Step-by-step explanation:
A) We are given;
Population proportion; p = 79% = 0.79
308 of the 370 respondents use social media in their job search. Thus;
Sample proportion; p^ = 308/370 = 0.8324
Let's state the hypotheses;
Null hypothesis; p ≤ 0.79
Alternative hypothesis; p > 0.79
Formula for the test statistic is;
z = (p^ - p)/√(p(1 - p)/n)
z = (0.8324 - 0.79)/√(0.79(1 - 0.79)/370)
z = 0.0424/0.021175
z = 2
From online p-value from z-score calculator attached and using; z = 2; significance value = 0.05; and one tailed distribution, we have;
P-value = 0.02275
B) similar to answer A above, Population proportion; p = 70% = 0.70
But 281 of the 370 respondents use social media in their job search. Thus;
Null hypothesis; p ≤ 0.70
Alternative hypothesis; p > 0.70
Also; Sample proportion; p^ = 281/370 = 0.7595
Formula for the test statistic is;
z = (p^ - p)/√(p(1 - p)/n)
z = (0.7595 - 0.70)/√(0.70(1 - 0.70)/370)
z = 0.0595/0.023824
z = 2.5
From online p-value from z-score calculator attached and using; z = 2.5; significance value = 0.05; and one tailed distribution, we have;
P-value = 0.00621
For positive integer n, the factorial notation n! represents the product of the integers from n to 1. (For example, 6! = 6*5*4*3*2*1.) What value of n satisfies the following equation?
5! X 9! = 12! x N
Answer:
The value of N that satisfies the equation is [tex]\frac{1}{11}[/tex]
Step-by-step explanation:
First we open the factorial of 12, to simplify the expression:
12! = 12*11*10*9!
So
5!*9! = 12!*N
5!*9! = 12*11*10*9!N
12*11*10N = 5!
Now we open the factorial of 5. So
12*11*10*N = 5*4*3*2*1
Since 5*2 = 10, 4*3 = 12, we have that:
12*11*10*N = 10*12*1
Now, simplifying by 10*12
11N = 1
[tex]N = \frac{1}{11}[/tex]
This is the value of N that satisfies the equation

Answer:
$6.18 :)
Step-by-step explanation:
617.5 cents would a bag of chips cost if it contained [tex]19[/tex] oz.
What is unitary method?Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
According to question,
Corn chips costs = [tex]32.5[/tex] cents per ounce.
A bag of chips of [tex]19[/tex] oz costs = 32.5 * 19
= 617.5 cents

Four fundamental factors affect the cost of money: (1) the return that borrowers expect to earn on their investments, (2) the preference of savers to spend their income in the current period rather than delay their consumption until some future period, (3) the risks associated with the investment, and (4) expected inflation. Consider the following statements that address these factors, and indicate which you think are true.
Statement 1: All things being equal, savers and investors expect to receive some amount of maturity premium as compensation for their deferred consumption.
Statement 2: Historical inflation rates, as opposed to expected future rates of inflation, should be used when calculating an investment’s nominal risk-free rate of return.
Statement 3: An investment that can provide a 10% return should attract more investment capital than an otherwise identical investment that can only provide a 6% return.
Statement 4: The inflation premium used to calculate the nominal interest rate on a five-year security should be equal to the rate of inflation expected in year 5 of the investment.
The true statements are:_______.
a. 1, 2, 3, and 4
b. 2 and 4
c. 1, 2, and 3
d. 1 and 3
Answer:
The true statements are 1 and 3
Step-by-step explanation:
Statement 1 -
All things being equal ,the savers and investors expect to receive some amount of maturity premium as compensation for their deferred consumption.
Statement 3 -
An investment that can provide a 10% return should attract more investment capital than an otherwise identical investment that can only provide a 6% return.
It is true because the return is higher than the return of identical investment therefore the higher returns will attract more investment.
Statement 2-
It is a false statement.
Historical inflation rates should not be used when calculating an investment’s nominal risk-free rate of return
But the real risk free rate and inflation premium is the part of prevailing interest rates that results from lenders compensating for expected inflation should be used
Statement 4-
It is a false statement.
The inflation premium used to calculate the nominal interest rate on a five-year security should not be equal to the rate of inflation expected in year 5 of the investment.
∴ we get
Statement 1 and 3 are true.

4. Dalia's entire room requires 20 cans of paint.
5. Dalia's entire room requires 5 cans of paint.
Hence statement 3 and 5 are true from the equation given in question.
What is equation?The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.
Types of Equations:
Linear Equation: More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1.
Quadratic Equation: This equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.
Cubic Equation: A third-order equation is this one. At least one of the variables in cubic equations needs to be raised to exponent 3.
Rational Equation: A fractional equation having a variable in the numerator, denominator, or both is referred to as a rational equation.
Number of cans used 1/10 part of room = 1/2
No. of cans paints used 1 part = 1/2 / 1/10 = 5
∵ 1/2 can paint is used = 1/10
∴ 1 can paint used = (1/10)*2 = 1/5
∴ 5 cans = 100%
3 cans used = (3/5)*100 = 60%

What number do you multiply to find this partial product 8×56
Answer: 8*56 is 448
you could also multiply 2⁶ x 7 to get 448
The number that you can multiply to find this partial product 8×56 is 8 and (50+6).
What is the partial product?The partial product method involves multiplying each digit of one integer by each digit of another, while each digit retains its position. For example, 23 x 42 becomes (20 x 40) + (20 x 2) + (3 x 40) + (3 x 2).
The number that you can multiply to find this partial product is,
8×(50+6)
= (8×50) + (8×6)
= 400 + 48
= 448
Hence, the number that you can multiply to find this partial product 8×56 is 8 and (50+6).
