QUESTION 8

Part A

Jerry is doing a project for his sociology class in which he tests the claim that the Pleasant View housing project contains family units of average size 3.3 people (the national average). A random sample of 64 families from Pleasant View project shows a sample mean of 3.8 people per family unit with sample standard deviation 1.3. Construct a hypothesis test to determine whether the average size of a family unit in Pleasant View is different from the national average of 3.3. Use a 0.01 level of signicance. State the null and alternative hypotheses. HO: ,u 75 3.3,Ha: u = 3.3 H0: [1 > 3.3, Ha: pt = 3.3 H0: ,1; = 3.3, Ha: [.1 > 3.3 H0: y = 3.3,Ha: y 7E 3.3 Continue to consider Question 8. Find the value of test statistic. O -3.08 O 3.08 O 24.6 O -24.6Continue to consider Question 8. Find the p-value. O 0.001 O 0.998 O 0.499 O 0.002Continue to consider Question 8. Based the p-value, what is your decision? O Reject HO, because p-value 0.01 O Do not reject HO, because p-value 0.01Continue to consider Question 8. If the true average size of family in Pleasant View is in fact 3.3 people (the national average), what type of error is it? No error Typel Type II Type III D Question 12 0.5 pts Continue to consider Question 8. Interpret the decision in the context. At 0.01 level of signicance... ' There is sufficient evidence that the average size of family units in Pleasant View is different from the national average. There is sufficient evidence that the average size of family units in Pleasant View is greater than the national average. ' There is insufficient evidence that the average size of family units in Pleasant View is equal to the national average. There is insufficient evidence that the average size of family units in Pleasant View is different from the national average
