let's perform the calculations in Excel: 1. Calculate the average car price: Enter the car prices (excluding the supercar outlier) into column A in Excel. In an empty cell, enter the formula: =AVERAGE(A1:A8) This will give you the average car price. 2. Determine the number of cars below the average: Count how many car prices are below the average manually or use the COUNTIF function in Excel. 3. Calculate the probability of a car falling below the average (p): Divide the number of cars below the average by 10 (total number of cars). 4. Now, let's use Poisson and Binomial distributions to calculate the probabilities: a) For Poisson Distribution: In Excel, use the formula =POISSON(4, p, FALSE) to calculate the probability of exactly 4 cars falling below the average. Use =POISSON(4, p, TRUE) to calculate the probability of fewer than 5 cars falling below the average. Use =1 - POISSON(6, p, TRUE) to calculate the probability of more than 6 cars falling below the average. Use =1 - POISSON(3, p, TRUE) to calculate the probability of at least 4 cars falling below the average. b) For Binomial Distribution: Use =BINOM.DIST(4, 10, p, FALSE) to calculate the probability of exactly 4 cars falling below the average. Use =BINOM.DIST(4, 10, p, TRUE) to calculate the probability of fewer than 5 cars falling below the average. Use =1 - BINOM.DIST(6, 10, p, TRUE) to calculate the probability of more than 6 cars falling below the average. Use =1 - BINOM.DIST(3, 10, p, TRUE) to calculate the probability of at least 4 cars falling below the average
