9)Test the claim that ?2< 44.8 if n = 28, s2 = 28, and ? = 0.10. Assume thatthe population is normally
distributed. Identify the claim, state the null and alternativehypotheses, find the critical value, find the standardized teststatistic, make a decision on the null hypothesis (you may use aP-Value instead of the standardized test statistic), write aninterpretation statement on the decision.
10)The heights (in inches) of 20 randomly selected adult malesare listed below.  Test the claim that the
variance is less than 6.25. Assume the population is normallydistributed. Use ? = 0.05. Identify the claim, state the null andalternative hypotheses, find the critical value, find thestandardized test statistic, make a decision on the null hypothesis(you may use a P-Value instead of the standardized test statistic),write an interpretation statement on the decision.
