Extracted text: 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 iis 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. Suppose the process of taking random samples of size 12 is repeated 1,000 times and a histogram of the 1,000 sample means lengths is created. The mean of the sampling distribution presented in the histogram will be approximately: O a. 22.8 O b, 23.2 O. 2.4 O d. We do not have enough information to find the mean of the sampling distribution.
