standard deviation of ox=15 TL.
a) Test the hypothesis Ho: (mean) µx = J TL with the alternate hypothesis that it is
less than J TL (H1: µx<J TL) at 5 % significance level (a). (To be solved by t student
distribution)
b) Test the hypothesis Ho: µx = J TL with the alternate hypothesis that it is not equal
to J TL (H1: ux+J TL) at 10 % significance level (a). (To be solved by normal
