What are examples of null and alternate hypotheses and conditions under which the null hypothesis is rejected.
Solution:-
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: u = 30
Alternative hypothesis: u 30
Note that these hypotheses constitute a two-tailed test.
If the p-value is less than significance level (), then we have to reject the null hypothesis.
If the p-value is greater than significance level (), then we failed to reject the null hypothesis.
