A cybersecurity team would like to detect the malwares in the software. They detect more than 42.5% malwares.From random sample of 200 softwares,76 had malwares.Calculate the value of test statistic. The value of test statistic is (Round your answer to three decimal places.)
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 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 fo representative 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 pag WebMD, 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 ce evidence 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.
