A random sample of 140 observations is selected from a binomialpopulation with unknown probability of success p. The computed value of p is 0.74.(1) Test Ho: p = 0.65 against H₁ : p > 0.65. Use a = 0.01.test statistic z =critical z scoreThe final conclusion isA. We can reject the null hypothesis that p=0.65 and accept that p > 0.65.B. There is not sufficient evidence to reject the null hypothesis that p = 0.65.(2) Test Ho: p = 0.65 against H₁ : p < 0.65. Use a = 0.01.test statistic z =critical z scoreThe final conclusion isA. There is not sufficient evidence to reject the null hypothesis that pB. We can reject the null hypothesis that p =(3) Test Ho: p = 0.55 against Ha: p0.55. Use a = 0.01.test statistic Z =positive critical z scorenegative critical z scoreThe final conclusion is= 0.65.0.65 and accept that p < 0.65.A. We can reject the null hypothesis that p = 0.55 and accept that p = 0.55.B. There is not sufficient evidence to reject the null hypothesis that p = 0.55.

A random sample of 23 bags of apples (marked as 10 pounds each) received by a large grocery chain tested out as having a mean of 9.2 pounds with a variance of 2.56 pounds. Test whether the true mean of all bags is under 10 pounds. Set up hypotheses. Perform the appropriate test by showing your formula. Interpret the results using a Type I (alpha) error of .05. Also provide the p value here. Also construct a 95% confidence interval around your sample mean (X bar) that should contain the true mean (mu). Also interpret this interval.
