1. Suppose that there are 5 children in a gymnastics class. One day, they count the number of steps each persontakes 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 whilewalking on their hands is 20 steps.(a) Identify the population and the parameter.population - children in the gymnastics classparameter - mean number of steps taken while walking on their hands(b) List all 10 possible SRSS of size n = 2. Calculate the mean number of steps taken while walking on theirhands for each sample.(c) Display the sampling distribution of the sample mean on a dotplot.
