I Professor Brown administered an achievement test, which as he remembers from years of experience, yielded a population mean score of 85. If his class of 25 students obtained a mean score of 89 with standard deviation score of 14, can the professor claim that his class is a superior class? Assume that the mean score is approximately normally distributed. Use a = 0.01

For the past several years, the Philadelphia Fire Departments has been keeping track of the number of fire hydrants that been opened illegally daily during heat waves. These data(rounded to the nearest 10) are given in the table below. Use the information to calculate how many hydrants the department should expect to be opened per day during the upcoming heat wave also find the Standard deviation of number of fire hydrants opened. Hydrants opened 20 30 40 50 60 70 Days 14 12 15 11 9 1
Part 1. The central limit theorem only applies when the original distribution is normal. True or false? Part 2. The shape of the t distribution is impacted by the size of the sample used to generate it. True or false?
