Question

1. Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. Choose the best conclusion. The owner of a football team claims that the average attendance at games is over 523, and he is therefore justified in moving the team to a city with a larger stadium. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms. a. There is not sufficient evidence to support the claim that the mean attendance is less than 523. b. There is sufficient evidence to support the claim that the mean attendance is less than 523. C. There is not sufficient evidence to support the claim that the mean attendance is greater than 523. d. There is sufficient evidence to support the claim that the mean attendance is greater than 523. For problems 2-6, use the 5 - step hypothesis testing procedure discussed in class. Determine whether to use a z-test or a t-test when testing means. You should use a calculator to find p- values for t-tests. 2. The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 lb. Assuming that o is known to be 121.2 lb, use a 0.10 significance level to test the claim that the population mean of all such employees weights is less than 200 lb. Step 1: Set up the null and alternative hypotheses. Step 2: Calculate the test statistic Step 3: Calculate the p-value Step 4: Make and justify a statistical decision using the p-value and level of significance level Step 5: Write a conclusion that addresses the context of the problem

Answer 1

Page No your Data d) since, p-value > d=0.1. We fail to reject Ho. weight of el The Paph Mean of all employees is not less than lbs. ㅏ 200
