Suppose a survey of 2,718 medical school interns found their average age to be 28.0 years, with standard deviation 3.7 years. (a) The distribution of ages is not normal. Will the distribution of sample mean, x, have an approximate normal shape? Yes No (b) If we standardize with sample standard deviation s instead of population standard deviation o, will the standardized sample mean follow an approximate z distribution? Yes No (c) Report an approximate 95% confidence interval for population mean...
QUESTIONS 1 points Save Ans To determine the average weight of carry-on luggage by passengers in airplanes, a sample of 35 pieces of carry-on luggage was weighed. The average weight was 28 pounds. Assume that we know the standard deviation of the population to be 6 pounds. Determine a 97% confidence interval estimate for the mean weight of the carry-on luggage. Provide the lower limit of the confidence interval. QUESTION 9 points Save Answer A random sample of 20 students...
