Use the information below to answer all questions: At a large company, the attitudes of workers are regularly measured with a standard test. The Til scores on the test are from 0 to 100, with higher score indicating greater satisfaction. The Art mean score over all companfs employees was 74, with a standard deviation of 8. Some time 0 l ago, the company adopted the policy that workers could spend one day per week working form home. Afterthe poliql had been in place for some time, a random sample of 80 workers was given the test. The sample mean was 76. Assume that the standard deviation is still 8. Can we conclude that the mean level of satisfaction is different since the policy change at the (1:005 level? 3 Question 1 1 pl: The assumptions are satised: It is a simple random sample The sample size is so it is more than required number 30. :) Question 2 1 pts Slate null hypothesis '40:\" [Select] v [Select] v State alternative hypothesis H141 [Select] v [Select] v 3 Question 3 1 MS This is [Select] v D Question4 1|\"s Compute the test statistic. Round to the nearest hundredth. 3 Question 5 1 pts Using the tables i] nd the psvalue (use the value of the test statistic that is rounded to the nearest hundredth). Do not round the psvalue [1] :) Question 6 1 pls Based on the test statistic and critical valuels) we [ Select ] v 3 Question 7 1 pts We conclude that a) There is enough evidence to reject the claim that the mean level of satisfaction is different since the policy change. b] There is enough evidence to support the claim that the mean level of satisfaction is different since the policy change. c) There is not enough evidence to reject the claim that the mean level of satisfaction is different since the policy change. d) There is not enough evidence to support the claim that tile mean level of satisfaction is different since the policy change
