"Are you getting your money's worth of cereal?" Sometimes, it appears that the cereal box you bought from a local supermarke is not quite full. To be sure that you are getting your money's worth, you decided to sample ten of the boxes, advertised as having 330 grams (g) of cereal, and found their weights (in grams) as follows. 329.94 330.05 330.23 329.58 330.21 329.87 329.65 329.85 329.89 330.03 a. Find a point estimate of the true mean weight of the cereal boxes. b. Construct a 90% confidence interval for the true mean weight of the cereal boxes to determine if you have sufficient evidence to indicate that you are getting your money's worth of cereal. Assume that the distribution of the weights of cereal boxes is normal.
