The amount of time Americans spend watching television is closely monitored by firms such as A.C. Nielsen because this helps to determine the advertising pricing for commercials. According to a recent survey, adult Americans spend an average of 2.34 hours per day watching television on a weekday. Assume the standard deviation for "time spent watching television on a weekday" is 1.91 hours. A) If a random sample of 60 adult Americans is obtained, what is the probability that the sample...

A social scientist claims that the average adult watches less than 26 hours of television per week. She collects data on 50 individuals’ television viewing habits and finds that the mean number watching television was 22.4 hours. If the population is normally distributed with a standard deviation of 8 hours, can we conclude at the 1% statistical significance level that she is right? Use the critical value and the test statistic to test the null hypothesis. Then calculate the p-value...

Each student in a random sample of 46 male students at a university in England and each student in a random sample of 38 female students from the same university kept a diary of how he or she spent time over a three-week period. For the sample of males, the mean time spent watching...
