a. Use the data given to test the following hypotheses. H0:m = 1200 Ha:m 7 1200 x = 1215,n = 113,s = 100,a = .10 b. Use the p-value to obtain the results. c. Solve for the critical value required to reject the mean.

When I copied and pasted it changed some of the equation lines and put letter like where the Ha:m is.. I guess when I copied it, it didn't understand the equation in the problem but its just placed a random letter their is all..
