Henrietta the office manager just finished an article that claimed your employees will be nicer to customers if they are given treats before they start their shift. Henrietta chose 10 random employees and wrote down how many 5-star ratings their customers gave them over the past month. Then, for the following month, Henrietta gave the employees each a small chocolate at the start of their shift, to see if those same employees would get more 5-star ratings. The results are shown on the table below. Test the claim that employees get more 5-star ratings with the candy than without. Assume the differences in the population are normally distributed. a. Have the requirements for this test been satisfied? Yes No (still complete the test anyway, for practice) H - Hypotheses b. The null and alternative hypotheses are e. Identify the significance level. D - Distribution and Data f. Identify the sample size. g. The appropriate distribution for this test is the h. Calculate the number of degrees of freedom. If this test does not use degrees of freedom, T - Test statistic and -value i. Calculate the test statistic. Round to 2 decimal places. j. Calculate p-value. Round to 4 decimal places. V - Verdict k. Make a decision. Reject the null hypothesis (and support the alternative hypothesis). Fail to reject the null hypothesis (and fail to support the alternative hypothesis). 1. State your conclusion about the original claim. There is sufficient evidence to support the claim. There is not sufficient evidence to support the claim. The results are inconclusive.
