### Question 5: [MULTIPLE CHOICE] which of the following is true about the elements in the sampling distributions you created? (a) Each element represents a mean square footage from a simple random sample of 50 houses. (b) Each element represents the square footage of a house. (c) Each element represents the true ,0. ulation mean of square footage of houses.
