A research group is curious about their city’s participation in flu shot clinics. They suspect that there is a difference between average amount of attendees at their city’s flu shot clinics when compared to their sister city. However, they must conduct a study to determine if that is true. From a sample of 20 clinics in the sister city, the sample mean of the clinic attendees is 156 and the sample standard deviation is 36. From a sample of 22 clinics in the researchers’ city, the sample mean of clinic attendees is 162 and the sample standard deviation is 41.
Determine if the researchers should accept or reject H0 under alpha = 0.05.
Note that the standard error is 11.8831 and the graph is two-tailed.
