Incorrect Question 2 0 / 5 pts A manufacturer makes chocolate squares that have a target weight of 8 9. Quality control engineers sample 30 chocolate squares to see whether H0: p = 8 vs. Ha: u i 8 where u is the true average weight of the chocolate squares. They calculate the sample mean of the 30 squares to be 8.3 9. Suppose the population standard deviation is 0.87 g and the true weight is 8.5 9. At the 5% level of significance, calculate the power for the test. For full credit, include all steps as described in class. Ans = 47-16% (Round to 2 decimals)
