QUESTION 6In a recent speech to students, the Dean of the College of Business claims that the average grade of students in the college is no longer 75. To conduct a test of the dean'sclaim, a randomly selected sample of 64 students revealed an average grade of 76 with a standard deviation of 5. Is there evidence that the average grade is no longer 75?Use a = 0.05.Ho: p= 75 vs H₁: #75.t-stat 1.6.p-value = 0.115.Do not reject Ho and there is not enough evidence to support the dean's claim.Ho: μ = 75 vs H₁: #75.Z-stat 1.6.p-value = 0.11.Do not reject Ho and thers is not enough evidence to support the dean's claim.ⒸHo: p = 75 vs H₁: # 75.z-stat 1.6.p-value = 0.11.Do not reject Ho and there is enough evidence to support the dean's claim.Ho: p=75 vs H₁: #75t-stat= 1.6.p-value = 0.115.Do not reject Ho and thers is enough evidence to support the dean's claim. QUESTION 7The health of employees is monitored by periodically weighing them. A sample of 54 employees has a mean weight of 184 lb and a standard deviation of 40.5 lb. At asignificance level 5%, we want to test the claim that the population mean of all such employees weights is less than 200 lb. Which test would be appropriate for thisproblem?O One-sample z-test.ⒸOne-sample t-test.Either one-sample z-test or one-sample t-test.ONeither one-sample z-test nor one-sample t-test.

Forty refrigerators from two different models of a refrigerator manufacturer are compared to see if the smaller model uses less energy than the larger model. The energy was measured in kilowatt hours per month (kwh/mo). From years of testing these models, it is known that the standard deviation of kwh/mo is 34 kwh/mo for the smaller model and 40 kwh/mo for the larger one. From this survey, the sample means and standard deviations are 125 and 34, and 90 and 40, respectively. If we conduct a hypothesis test, the decision and conclusion are Group of answer choices Do not reject the null hypothesis and conclude that the average kwh/mo are the same. Reject the null hypothesis and conclude that the average kwh/mo are different. Reject the null hypothesis and conclude that the average kwh/mo for the smaller refrigerator is higher than for the larger model. Do not reject the null hypothesis and conclude that the average kwh/mo for the smaller refrigerator is higher than for…
