Suppose there are 5 children in the gymnastics class. One day they count the number of steps each person takes while walking on their hands until they lose balance and fall 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). List all 10 possible RSRs of size n=2. Calculate the mean number of steps taken while walking on their hands for each sample.
c). Display the sampling distribution of the sample mean on a dotplot.

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
