We wish to gather some information relating to the average time a hospitalized Eagle Flu patient remains in the hospital. We randomly sample 16 cured formerly hospitalized Eagle Flu patients and these were the number of days spent in the hospital: 6.09, 8.04, 6.43, 8.58, 10.34, 5.40, 9.87, 9.24, 9.18, 5.06, 5.39, 5.89, 11.91, 8.94, 5.68, 9.85Many surveys of flu hospital stays show that hospitalization length is normally distributed. So, we assume that our sample comes from a normal population with unknown mean of μ days and an unknown standard deviation of σ days. We would like to test whether the average hospital stay length is less than 8.1 days..The null hypothesis is thus H0:μ=8.1 . We will test this against the alternative Ha We want to test at the 8% level.Let x = the sample mean and s = the sample standard deviation.f) Calculate the critical value, tstar, for your test.(negative value)
