The mean age of all 2531 students at a small college is 22.8 years with a standard deviation of 3.7 years, and the distribution is right-skewed. A random sample of 3 students' ages is obtained, and the mean is 23.2 with a standard deviation 3.2 years. Complete parts (a) through (c) below. u= 22.8 o = 3.7 x= 23.2 s= 3.2 (Type integers or decimals. Do not round) b. Is u a parameter or a statistic? The value of u is a parameter because it is found from the population. c. Are the conditions for using the CLT (Central Limit Theorem) fulfilled? Select all that apply. O A. No, because the big population condition is not satisfied O B. No, because the random sample and independence condition is not satisfied. O c. No, because the large sample condition is not satisfied O D. Yes, all the conditions for using the CLT are fulfilled. What would be the shape of the approximate sampling distribution many means, each from a sample of 3 students? O Right-skewed Left-skewed Normal The shape cannot be determined.
