I want to verify that I'm doing things correctly. My result is to reject the null. Am I on the right track??

Alt Hypothesis: H1: µ≠170

Using a significance level of .05

I'm using a one-sample z test and my results were z=2.19.

The mean weight of Minnesota males are heavier than males in general.

- The following data was obtained from a randomly selected sample of 20-year-old, 6-foot-1-inch males from Minnesota. This sample of 25 males had a mean weight of 177 lb. Based on this sample, are Minnesota males heavier than males in general? The mean weight of all U.S. males is 170 lb., and the population standard deviation is 16.
