Question:
Subway passengers spend an average of $6 a day on subway fares. The standard deviation of the expenditure is $2.5. A simple random sample of 40 passengers is taken.
- What are the expected value, standard deviation, and shape of the sampling distribution of the sample mean?
- What is the probability that the sample mean will be between $4 and $7?
