Stacked Red Rocks Park in Morrison, Colorado, is a naturally formed, rock, open-air amphitheater located 6450 ft above sea level. A random sample of events held at this site in summer 2018 was obtained, and the attendance for each was recorded. The summary statistics were sample mean x = 8722, sample standard deviation s = 460.4, and sample size n = 11. Assume the distribution of attendance is normal and use the significance level a = 0.01. How large a sample size n would be necessary for this test to be significant (assuming x and s remain the same)? (Give your answer as a whole number. Give the minimum possible value of n.) @ Macmillan Learning 0 n 2 Incorrect
