The mean weight of chips put into the bags on the production line is supposed to be 28.3 grams. The manager selects a random sample of 6 bags from the production line; he carefully weighs the contents of each bag; the weights are as follows (in grams): 29.3, 28.2, 29.1, 28.7, 28.9, 28.5. Assume that the distribution of the weight of chips put into bags can be approximated with a normal model. Perform the appropriate hypothesis test at significance level α = .05 and answer the following questions. Calculate the sample mean y and sample standard deviation s to 2 decimal places. Question 1. What is the value of the test statistic t ? 1 Question 2. Choose the correct statement concerning the P-value for this test. 2 .025 < P-value < .05 P-value < -1.96 .01 < P-value .05 P-value 1.645 Question 4. What type of error might you be making? 4 Type II error or Type I error
