A marketing company wants to estimate the proportion of consumers in a certain region of the country who would react favorably t
Sindrei [870]

The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271

Explanation:

When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-

n=0.25(\frac{z^{*} }{E} )^{2}

where E = Margin of error.

z* = Critical z-value.

As per given , we have

E = 5%=0.05

Confidence level = 90%

The critical value of z at 90% is 1.645  (By z-table)

Put all values in the formula , we get

n=0.25(1.645/0.05)²

n=0.25(32.9)²

n=270.6025≈271

Thus, the minimum sample size needed = 271

Hence , the correct answer is 271 .

Ganezh [65]

Answer:

 B. No; The IRR is less than the required return by about 1.53 percent

Explanation:

The internal rate of return is the discount rate that equates the after tax cash flows from an investment to the amount invested.

The IRR can be calculated using a financial calculator:

Cash flow in year zero = -$42,000

Cash flow in year one = 15,300

Cash flow in year two = 28,400

Cash flow in year three = 7,500 

IRR = 11.47%

A project should be chosen if the IRR is greater than the required return

The IRR is less than the required return so the project should be rejected.

To find the IRR using a financial calacutor:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. After inputting all the cash flows, press the IRR button and then press the compute button.
