.18 Student Ages The mean age of all 2550 students at a small ollege is 22.8 years with a standard deviation is 3.2 years, and the istribution is right-skewed. A random sample of 4 students' ages is btained, and the mean is 23.2 with a standard deviation of 2.4 years. a. = ? = ? x = ? s = ? b. Is a parameter or a statistic? c. Are the conditions for using the CLT fulfilled? What would be the shape of the approximate sampling distribution of many means, each from a sample of 4 students? Would the shape be right-skewed, Normal, or left-skewed? .18 Student Ages The mean age of all 2550 students at a small ollege is 22.8 years with a standard deviation is 3.2 years, and the istribution is right-skewed.
