A study is dоne аt а lаrge cоllege tо look at the mean time it takes a student to find parking in the garage in the morning. A random sample of 45 cars will be timed from when they enter the garage to when they park. It is found that the mean time is 12.4 minutes with a standard deviation of 3.6 minutes. Choose the all appropriate conditions below that confirm that the Central Limit Theorem will apply in this problem. Only the conditions used in this class will be considered correct.

Complete the table by finding P(4), the probability that a student is taking 4 classes. [answera] b. Is the random variable, X, continuous or discrete? [answerb] c. What is the most likely number of classes a student at this college is taking? If rounding is necessary, round to two decimal places. [answerc] d. What is the expected number of classes a student at this college is taking? If rounding is necessary, round to two decimal places. [asnwerd] e. What is the standard deviation in the number of classes a student at this college is taking? If rounding is necessary, round to two decimal places. [answere] f. Which of the following interpretations of the expected value is correct? [exp]
