More Used Car Sales A used car dealership uses past data to estimate the probability distribution for the number of cars they sell in a day. The probability distribution of X is given in the table below. Cars sold in a day x 0 1 2 3 4 p(x) 0.25 0.31 0.2 0.15 0.09 What is the probability that the dealership sells no cars on three consecutive days? (Assume daily sales are independent.) Round your answer to four decimal places.
Sales records indicate that the selling price of used cars at a large car dealership are skewed right, with a mean of $17000 and a standard deviation of $11000 Explain whether Table Z (the normal distribution table) could be used to find the probability that a single used car at this dealership would sell for less than $20000 For a random sample of 70, the mean for the sampling distribution of average price would be and the standard deviation would...
