In a study of academic procrastination, the authors of a paper reported that for a sample of 431 undergraduate students at a midsize public university preparing for a final exam in an introductory psychology course, the mean time spent studying for the exam was 7.54 hours and the standard deviation of study times was 3.90 hours. For purposes of this exercise, assume that it is reasonable to regard this sample as representative of students taking introductory psychology at this university.

A healthcare information company is interested in estimating the average charge for a standard patient visit to a chiropractor in Maryland, after applying the discount negotiated with a large HMO plan. Data is collected from 16 randomly selected chiropractic practices in Maryland, and the following are some summary statistics:- Mean charge: 25.50 USD- SD of charges: 2.10 USDAssuming the charge data is normally distributed for all chiropractic practices in Maryland, estimate a 95% confidence interval for the mean amount charged by Maryland chiropractors (t (15, 0.05) = 2.13):
1. If a pilot study reveals the mean size of homes in a town to be 120 square meters with a standard deviation of 40 square meters, how many homes would have to be sampled if we wanted our estimate of the mean to be accurate within 5 square meters, 98 times out of 100? 2. In a random sample of 200 households that recently visited Intercity Shopping Centre, it is found that 100 also visited the Thunder Centre big box development on the same shopping trip. Using a confidence level of 90 percent, estimate the proportion of shopping trips to Intercity that involve cross shopping at the Thunder Centre.
