The average number of prescriptions filled at a pharmacy per person in the United States in 2019 was 11.6. An Illinois health official wants to test whether or not the mean number of prescriptions per capita in Illinois is different than 11.6. They randomly sample 104 Illinois residents and compute a sample mean of 10.9 prescriptions per person. Assume that the population standard deviation is known to be σ = 3.2 prescriptions per person. The official will conduct the test at a 5% significance level. c. Compute test statistic (z-value). d. Compute P-value
