Question: The following table includes the weights of thirteen red M&M candies randomly selected from a bag containing 465 M&Ms. Those weights have a mean of x = 0.8635 grams & a standard deviation of 5 = 0.0576 grams. The bag states that the net weight of the contents is 396.9 grams- [Therefore, we can calculate 396.9 + 465 = 0.8535g per candy in order to provide the amount claimed.]

0.751	0.841	0.856	0.799	0.966	0.859	0.857
0.942	0.873	0.809	0.890	0.878	0.905

A production manager believes that consumers are getting more total weight in M&Ms than the amount indicated on the label. Use the sample data provided with an a = 0.10 significance level to test the claim of the production manager- that each individual M&M has a mean that is actually greater than 0.8535 g per candy.

[A] What type of test is this? Right-tailed, Left-tailed,or two-tailed? Which table will you use to find the critical value? What is the critical value for this hypothesis test?

[B] Perform the last step in the hypothesis test. Do you reject the null hypothesis or fail to reject the null hypothesis?

[C] According to your conclusion in step b, do the sample data provide significant evidence to conclude that the mean weight of individual M&Ms is greater than 0.8535 g?
