can you please help me with this? Thanks in advance

A group of students got the following scores in a test: 6, 9, 12, 15, 18, and 21 Consider samples of size 3 that can be drawn from this population. a. List all the possible samples and the corresponding mean. Sample Mean b. Construct the sampling distribution of the sample means. Sampling Distribution of Sample Means Sample Mean Frequency Probability P(X) c. Draw a histogram of the sampling distribution of the means. A finite population consists of 8 elements. 10 10 10 10 10 12 18 40 a. How many samples of size n - 2 can be drawn from this population? b. List all the possible samples and the corresponding means. Sample Mean C. Construct the sampling distribution of the sample means. Sampling Distribution of Sample Means Sample Mean Probability X Frequency P(X) d. Draw a histogram of the sampling distribution of the means
