complete solutions correct answers key 

An entrepreneur is considering the purchase of a coin-operated laundry. The current owner claims that over the past five years, the mean daily revenue was $675 with a population standard deviation of $75. A sample of 30 days reveals a daily mean revenue of $625. If you were to test the null hypothesis that the daily mean revenue was $675, at a significance level of 0.05, your hypotheses would be

H0: ≥ 675 versus H1: < 675.

H0: μ = 675 versus H1: μ ≠ 30.

H0: ≤ 625 versus H1: > 675

H0: μ ≥ 675 versus H1: μ < 675.

Home Depot is considering opening a new store in an area that currently does not have any such stores. The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area own a pickup trick. It conducts a telephone poll of 300 randomly selected households in the area and finds that 96 have a pickup truck. At a significance level of 1%, state the test of hypothesis that is of interest to Home Depot.

H0: π ≤ 5,000 versus H1: μ > 5,000

H0: μ ≤ 5,000 versus H1: μ > 5,000

H0: π ≤ 0.32 versus H1: π > 0.32

H0: π ≤ 0.25 versus H1: π > 0.25
