Ninety five cities provided information on vacancy rates (in percent) in local apartments in the following frequency distribution. The sample mean and the sample standard deviation are 10% and 4.0%, respectively. (You may find it useful to reference the appropriate table: chi-square table or F table) Vacancy Rate Less than 6 Frequency 11 6 up to 9 9 up to 12 24 38 12 or more 22

c. Find the p-value.
O p-value < 0.01
O p-value 20.10
O 0.05 s p-value < 0.10
O 0.025 s p-value < 0.05
O 0.01 s p-value <0.025
d. What is the conclusion?
O Reject Ho; there is not enough evidence to support the claim that the vacancy rates are not normally distributed
O Reject Ho, there is enough evidence to support the claim that the vacancy rates are not normally distributed
O Do not reject Ho; there is enough evidence to support the claim that the vacancy rates are not normally distributed
O Do not reject Ho; there is not enough evidence to support the claim that the vacancy rates are not normally distributed

a. Apply the goodness-of-fit test for normality at the 10% significance level. Do the sample data suggest that vacancy rates do not
follow the normal distribution? First, select the appropriate null and alternative hypotheses.
Ho: Vacancy rates are not normally distributed with a mean of 10% and a standard deviation of 4%.; HA Vacancy rates are
normally distributed with a mean of 10% and a standard deviation of 4%.
Ho: Vacancy rates are normally distributed with a mean of 10% and a standard deviation of 4%.; HA: Vacancy rates are not
normally distributed with a mean of 10% and a standard deviation of 4%.
b. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3
decimal places.)
