spayn [35]

Answer:

1. Referring to Problem , the manager wants to know the value of the population so the manager uses the sample to estimate the population proportion.

a. True

2. Referring to Problem , point estimate of the population proportion is = 0.45.

a. True

3. Referring to problem , the sample proportion is = 0.45.

b. False

4. Referring to Problem, the manager wants to know the value for the population so the manager uses the sample to estimate the population value

b. False

5. Referring to Problem , the parameter of interest is 54/120 = 0.45.

a. True

Explanation:

a) Data and Calculations:

Sample of potential consumers = 120

Proportion of the sample who recognize the product = 54

Confidence level = 95%

Confidence interval = 0.36 to 0.54

Point estimate = 54/120 = 0.45

b) A point estimate of a population parameter estimates the population parameter as a single value. The point estimate of the sample mean, x, is also the point estimate of the population mean, μ. To get the sample proportion, one needs to know the population value. The sample value divided by the population value gives the sample proportion.

What is the present value of an annuity that pays $58 per year for 13 years and an additional $1,000 with the final payment

Doss [256]

Answer:

$882.03

Explanation:

Interest rate used is 7.23%

Present value is the sum of discounted cash flows

Present value can be calculated using a financial calculator

Cash flow in year 1 to 12 = 58

cash flow in year 13 = 1058

I = 7.23

To find the PV using a financial calculator:

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 NPV button, input the value for I, press enter and the arrow facing a downward direction.

3. Press compute
