Many people now turn to the internet to get information on health-related topics. A research article used Flesch reading ease scores (a measure of reading difficulty based on factors suchlength and number of syllables in the words used) to score pages on Wikipedia and on WebMD, Higher Flesch scores correspond to more difficult reading levels. The paper reported that forepresentative sample of health-related pages on Wikipedia, the mean Flesch score was 26.5 and the standard deviation of the Flesch scores was 14.5. For a representative sample of pagWebMD, the mean score was 43.5 and the standard deviation was 19.2. Suppose that these means and standard deviations were based on samples of 40 pages from each site. Is there ceevidence that the mean reading level for health-related pages differs for Waipedia and WebMD? Test the relevant hypotheses using a significance level of 0.05.

Most graduate schools of business require applicants for admission to take the Graduate Management Admission Council's GMAT examination. Scores on the GMAT are roughly normally distributed with a mean of 527 and a standard deviation of 112. If a prestigious business school will only take those students who score in the top 5%, what score would you need to have to be accepted? You would need a score of or higher (round to the nearest whole number)

A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of 128 ounces and a standard deviation of 0.40 ounce. You randomly select 45 cans and carefully measure the contents. The sample mean of the cans is 127.9 ounces. Does the machine need to be reset? Explain your reasoning. it is that you would have randomly sampled 45 cans with a mean equal to 127.9 ounces, because it within the range of a usual event, namely within of the mean of the sample means.
