1. A sample of 40 Los Angeles pharmacies sells the Tamiflu 75mg prescription drug for about $137 for a 1 month supply (s = $30.2). The average pharmacy nationally sold the drug for $150. Using the hypothesis test (6 steps) at ? = .05, test whether there is a significant difference in price.
2. How significant are the results? What range of p-values would it fall under?
3. Calculate a 95% confidence interval and interpret the results.
