Question 1: The average fill volume from a random sample of 49 bottles of an energy drink is 32.8 ounces; the standard deviation among the individual fill volumes is3.5 ounces. Determine a 95 percent confidence interval for the mean fill weight.
Question 2: Continuation of previous problem. Determine the probability value for testing the research hypothesis that the mean fill volume is less than 33 ounces. Use the sample information in the previous problem and state your conclusion assuming a significance level of 5 percent.
