- How many days were used in this study?
- Based on this study, what was the expected number of cars sold
per day?
- What is the probability of selling 5 cars in a day?
- What was the variance in the expected number of cars sold per
day?
- What was the standard deviation in the expected number of cars
sold per day?
- What is your coefficient of variation for the sales?
- How many cars were sold during the periods you are
studying?
- For the next 50 days, what will be the expected number of cars
sold?
