Katy and Bonnie decide to buy some Krispy kernel microwave popcorn they are completely bowled over by the high-tech graphics on the package showing how the popping-times for a bag of this carefully produced product are normally distributed with a mean of 3.0 minutes ( and yet they know enough about statistics to be skeptical about untested claims about the value of a population mean). Sampling the product themselves, they obtained the following popping times in minutes for their sample of five bags; 3.9 2.8 3.4 4.1 3.3 A. Determine the following values if possible from the information given if not possible write " N/A" X= u= o= s= n= B. Find a 90% confidence interval for the true mean Popping time for this product. C. Is it reasonable to conclude that the mean Popping time is 3.0 minutes as advised. Why or why not?
