The mean age of all 2550 students in a small community college is 22.8 years with a standard deviation of 3.2 years, and the distribution is non-normal. A random sample of 12 students' age is obtained, and the mean is 23 2 years with a standard deviation of 2.4 years In this example, the numerical values 22.8 and 2.4 are O a. Both are statistics O b.22.8 is a statistic, 2.4 is a parameter Oc. Both are parameters O d. 22.8 is a parameter, 2.4 is a statistic
