QUESTION 14 M&M's You are part of a regulatory agency that is investigating the accuracy of the advertised weight of a 10ounce bag of M&M's. Suppose you take a sample of 25 bags of M&M's and weigh each bag. The mean weight from your sample is 9.7 ounces with a sample standard deviation of 0.8 ounces. Assume the population of M&M bag weights is normally distributed. M&M's. Conduct a hypothesis test to evaluate whether or not, on average, a bag of M&Ms is at least 10 ounces. Which ofthe following is true? C The test statistic is z = 1.875 C The test statistic is t = 1.875 C The test statistic is t = can A None of the above. QUESTION 15 M&M's You are part of a regulatory agency that is investigating the accuracy of the advertised weight of a 10-ounce bag of M&M's. Suppose you take a sample of 25 bags of M&M's and weigh each bag. The mean weight from your sample is 9.7 ounces with a sample standard deviation of 0.8 ounces. Assume the population of M&M bag weights is normally distributed. M&M's. Imagine that you are using Stata to assist you with the hypothesis test for whether or not, on average, a bag of M&Ms is at least 10 ounces. If the program reports a p-value of 0.0, what can you conclude? A There is statistical proof that M&M's weigh at least 10 ounces. A There is statistical proof that M&M's do n_ot weigh at least 10 ounces. A An error in the analysis must have occurred because p-values cannot be 0.0. A The claim that M&M's weigh at least '10 ounces can be rejected at the 5% level but not the 1% level. A The claim that M&M's weigh at least 10 ounces can be rejected at any conventional level of signicance. A None of the above. 1 points 1 points Save Answer Save
