Ninety four 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 8% and 4.0%, respectively. (You may find it useful to reference the appropriate table: chi-square table or Ftable) Vacancy Rate Less than 6 6 up to 9 9 up to 12 12 or more a. Apply the goodness-of-fit test for normality at the 5% significance level. Do the sample data suggest that vacancy rates do not follow the normal distribution? First, select the appropriate null and alternative hypotheses.
