Sweet Rush is an ice cream shop chain that has locations all across the nation. Customers at Sweet Rush have the option of ordering 1, 2, or 3 scoops of icecream in their cone. The mean number of scoops ordered is u = 2.86, with a standard deviation of o = 0.23. Suppose that we will take a random sample ofn=7 ice cream cone orders and record the number of scoops for each. Let x represent the sample mean of the number of scoops for the 7 ice cream coneorders. Consider the sampling distribution of the sample mean x.Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed.(a) Find u- (the mean of the sampling distribution of the sample mean).H- = ||(b) Find o- (the standard deviation of the sampling distribution of the sample mean).=0?

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual.
