New Orleans' Coca Cola bottling center wants to determine whether the mean amount of product in a 12 oz can of Coke is actually 12 ounces. Thus, the null and alternative hypotheses are Ho: mu is equal to 12 ounces Ha: mu is not equal to 12 ounces You want to be extra sure that you aren't underfilling (which would open you up to a lawsuit). Being risk averse, you set out to conduct a hypothesis test at a stringent 99% level. Fill rates are distributed Normally. You take a sample of 50 different Coke cans and carefully measure the amount of product. From this sample, you calculate an avg fill of 12.3 ounces, with a standard deviation of 0.75 ounces. What do you conclude about the average amount of Coke product in the cans? Group of answer choices a. There is sufficient evidence to conclude that you are not filling to 12 ounces on average. b. There is NOT sufficient evidence to conclude that you are under- or over-filling on average.
