According to a survey, 21% of the car owners said that they get the maintenance service done on their cars according to the schedule recommended by the auto company. Suppose that this result is true for the current population of car owners.

Find to 3 decimal places the probability that exactly 4 car owners in a random sample of 13 get the maintenance service done on their cars according to the schedule recommended by the auto company. Use the binomial probability distribution formula.

A recent national survey stated 70% of college students said they get less than the recommended amount of sleep every night. A statistician decides to test this claim against the suspicion that the percentage is too high. The statistician randomly sampled 1500 college students from the population of college students and determines that 1020 college students stated they don’t get the recommended amount of sleep. Perform a hypothesis test to answer the question: Do the sample results support the statistician’s...
