Solution:-
25) (d) Reject H0 and accept Ha at =
5%.
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: u < x
Alternative hypothesis: u > x
Note that these hypotheses constitute a one-tailed test.
z = 2.09
zcritical = 1.65
Interpret results. Since the z-value (2.09) lies in the rejection region, hence we have to reject the null hypothesis.
