A roll of Life Savers candies contains 14 pieces. Suppose the individual candies have a mean weight of 0.09 ounces and standard deviation of 0.01 ounces. Find the mean and standard deviation of the total weight of the roll of candies, ignoring the weight of any packaging material. O mean = 1.26 ounces, standard deviation = 0.14 ounces O mean = 0.09 ounces, standard deviation = 0.037 ounces O mean = 1.26 ounces, standard deviation = 0.037 ounces O mean = 0.09 ounces, standard deviation = 0.14 ounces O mean = 1.26 ounces, standard deviation = 0.0014 ouncesPorsche Cars North America keeps detailed records on all current Porsche owners. The marketing director takes a random sample of 9 customer records and finds that the average age of a Porsche owner is 52.8 years with a standard deviation of 6.1 years. Assuming all conditions of inference were met, what is a 95% confidence interval estimate for the average age of all Porsche owners?
