According to the California Educational Code (http://www.cde.ca.gov/ls/fa/sf/pegui- demidhi.asp), students in grades 7 through 12 should receive 400 minutes of physical education every 10 school days. A random sample of 48 students has a mean of 385 minutes and a standard deviation of 53 minutes. Test the hypothesis at the .05 level of significance that the sampled population satisfies the requirement.

Is this the right way to solve this problem? If not can you please explain how I find the answer please? Thank you!
