Boxes of crackers are labeled as containing 16 ounces. In a random sample of 40 boxes of a certain brand, the mean weight was 15.95 ounces. Assume o = 0.05 ounce. a) Construct a 95% confidence interval for the population mean weight of a box of crackers for this brand. To show work, write out the following: - Write out the number of the row from the Formula Sheet that's used to compute the lower and upper bounds. - The calculator program used and the numbers you that you plugged in with their corresponding variables/symbols b) As shown during class, use a sentence to interpret your confidence interval from (a). No explanation is needed for this part. Include the following in your interpretation: - The confidence level. - The population parameter of interest (in the context of the problem) - The lower and upper bounds, along with the units c) Someone claims that the mean weight of a box of crackers for this brand is less than 16 ounces. Based on your confidence interval from (a), do you agree with this claim? Briefly explain why or why not using a complete sentence
