Description: Test the claim that the mean GPA of night students is significantly different than 2 at the 0.01 significancelevel.The null and alternative hypothesis would be:Но: р > 0.5 Нo: 2 H1:p > 0.5 H1:µ # 2 H1:p+ 0.5 H1:µ

The summary of statistics is, The test is two tailed testThe value of test statistic is, The degree of freedom is, df=n-1 =55-1 =54 The p-value of the hypothesis test is,Since the p-value less than the level of significance, so we reject the null hypothesis at specified significance level. Conclusion: Hence there is sufficient evidence to support the claim that mean GPA of night students is significantly different than 2.

Under what circumstances is a t statistic used instead of a z-score for a hypothesis test? Justin wants to know whether a commonly prescribed drug does improve the attention span of students with attention deficit disorder (ADD). He knows that the mean attention span for students with ADD who are not taking the drug is 2.3 minutes long. His sample of 12 students taking the drug yielded a mean of 4.6 minutes. Justin can find no information regarding σx , so he calculated s2x =1.96. Identify the independent and dependent variables. In a sentence, state the null hypothesis being tested. c. Using symbols, state the null and alternative hypotheses
