Suppose that there are 5 children in a gymnastics class. One day, they count the number of steps each person takes while walking on their hands until they lose balance and come down. The results are Ashley (20), Brittany (8), Carol (22), Darla (26), and Erica (24). The mean number of steps these children took while walking on their hands is 20 steps. a) Identify the population and parameter.

b)On separate paper, list all possible SRSs of size n = 2. Calculate the mean number of steps taken while walking on their hands for each sample. Display the sampling distribution of the sample mean on a dotplot.
