QUESTION 2. Billy’s Fizzy Flavours Inc. wants to estimate the average volume per can of Crazy 88 Cola with 90% confidence. (a) In practice, the soft drink producer does not know the population mean or population standard deviation of the volume per can. However, for the purpose of this question we will assume the volume per can is normally distributed with a mean of 353 mL and a standard deviation of 2 mL. Use this information and the Excel procedure...
