Question

Researchers published a study that investigated the degree to which a country's households waste food. The researchers used data from 3,637 households to measure the percentage of food acquired that is wasted per household. For this sample of 3,637 households, the mean amount of food wasted is 33.7% with a standard deviation of 16.2%. Complete parts a and b. a. Find a 99% confidence interval for ?, the true mean amount of food wasted by all households. (%, %) (Round to one decimal place as needed.) b. An economist claims that ? is less than 32%. Do you agree? Explain. A. Yes, because 32% is outside the confidence interval. B. Yes, because 32% is inside the confidence interval. C. No, because 32% is outside the confidence interval. D. No, because 32% is inside the confidence interval.
