6. A video game company sends out shipments to its various stores with a mean cargo size of 75 games, and a standard deviation of 4.8 games. What is the probability that a store chosen at random will receive a shipment of between 65 and 85 games (assume a normal distribution)? 7. Gwen walks the same route home every day, and she often finds coins lying on the ground. There is a 42% chance that Gwen will find one dime on her way home. Gwen walked home 30 times this past month. a) Is it possible to use the normal approximation to the binomial distribution? How do you know? b ) Assuming she never found more than one dime each day, what is the probability she found more than 8 dimes this past month
