Dover Motors is a car dealership that sells new and used cars. Suppose they sold 140 used cars during the most recent quarter. The average selling price was $10,325 with a standard deviation of $2,880. A random sample of 60 used cars from this population was selected. Answer the following questions, performing all computations with Excel. a. Compute the standard error of the sample mean of selling price at the dealership. b. Compute the probability that the sample mean selling price is less than $10,000 c. Compute the probability that the sample mean selling price is more than $9,500 d. Compute the probability that the sample mean selling price is between $9,300 and $10,800
