Question

A chain of grocery retailers is considering opening a new store in an area that currently does not have any such stores. Currently the rule is that a store will open if there are 7,500 of the 25,000 households in the area have a favorable view of its chain. To test that there is a greater proportion demand, it conducts a telephone poll of 300 randomly selected households in the area and finds that 96 have a favorable view. 1. Which of the following (A,B,C,or D) would be the correct hypothesis statement? A. H0: ? ? 0.30 H1: ? > 0.30 B. H0: ? ? 0.32 H1: ? > 0.32 C. H0: ? ? 7,500 H1: ? > 7,500 D. H0: ? ? 7,500 H1: ? > 7,500 To test at 95% confidence, it conducts a telephone poll of 300 randomly selected households in the area and finds that 96 have a favorable view. 2. The critical value is State + - or +- 3. The value of the test statistic in this problem is... (2 decimal places) 4. The p-value associated with the test statistic is... (4 decimal places) 5. At a 5% level of significance, will the decision be to reject H0? (Yes/No)
