11.1 Hypothesis Testing: Mean, z-test
Lab 11.1.1
A government official claims that the average recovery time for Covid19 patients with mild symptoms is less than 2 weeks. A random sample of 25 patients with mild symptoms has a mean recovery time of 2.4 weeks with standard deviation of 0.9 weeks. Assume recovery time is normally distributed with standard deviation of 0.5 ( ) weeks. Test the government's official claim at α of 0.05. Use the z_test_mean function above.
