- Grace Floral Shop claims that their average daily earnings is $497. An auditor wants to determine whether this claim is true. The auditor randomly selected a sample of 100 days and found that the sample mean earnings was $495 with a sample standard deviation of 9.75. Calculate the 97% confidence interval for the population mean daily earning. Assist the auditor in conducting a hypothesis test, at the 3% level of significance, to determine whether the claim about their average daily earnings was overstated. State the null and the alternative hypothesis for this test. Using the p-value approach, state the decision rule for this Calculate the value of the test statistic for this test. Calculate the p-value for this test? State the conclusion of this test. Give reason for yourA statistics instructor is interested in the ability of students to assess the difficulty of a test they have taken. This test was taken by a large group of students, and the average score was 78.5. A random sample of eight students was asked to predict this average score. Their predictions were as follows:72 83 78 65 69 77 81 71Assuming a normal distribution, test the null hypothesis that the population mean prediction would be 78.5. Use a two-sided alternative and a 10% signifi- cance level.Given the following hypotheses: H0: μ ≤ 8 H1: μ > 8 A random sample of 10 observations is selected from a normal population. The sample mean was 11 and the sample standard deviation was 4.6. Using the 0.1 significance level: State the decision rule. (Round your answer to 3 decimal places.) Compute the value of the test statistic. (Negative answers should be indicated by a minus sign. Round your answer to 3 decimal places.) What is your decision regarding the null hypothesis?

Does a 95% confidence interval include β1=1? A.Yes, since the value of the t-statistic for the null hypothesis β1=1 is −2.50 and the 5% critical value of the augmented Dickey-Fuller statistic is −2.86, the null hypothesis is not rejected. Thus β1=1 is in the 95% confidence interval. B.No, the interval, calculated as β1±1.96SEβ1, is from 0.91 to 0.99. C.No, since the value of the t-statistic for the null hypothesis β1=1 at the 5% level is −2.50. D.No, because the critical value of the augmented Dickey-Fuller statistic at the 5% significance level is −2.86.
