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 such as sentence length 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 for a representative sample of health-related pages on Wikipedia, the mean Flesch score was 26.1 and the standard deviation of the Flesch scores was 14.8. For a representative sample of pages from WebMD, the mean score was 43.4 and the standard deviation was 19.1. Suppose that these means and standard deviations were based on samples of 40 pages from each site. Many people now turn to the Internet to get information on health-related topics.

Question

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 such as sentence length 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 for a representative sample of health-related pages on Wikipedia, the mean Flesch score was 26.1 and the standard deviation of the Flesch scores was 14.8. For a representative sample of pages from WebMD, the mean score was 43.4 and the standard deviation was 19.1. Suppose that these means and standard deviations were based on samples of 40 pages from each site. Many people now turn to the Internet to get information on health-related topics.
