Facebook: A study showed that two years ago, the mean time spent per visit to Facebdok was 20.0 minutes. Assume the standard deviation is o =5.0 minutes. Suppose that a simple random sample of 109 visits was selected this year and has a sample mean of x =21.0 minutes. A sodial scientist is interested to know whether the mean time of Facebook visits has changed. Use the a= 0.10 level of significance and the P-value method with the TI-84 calculator. (a) State the appropriate null and alternate hypotheses. (b) Compute the P-value. (c) State a conclusion. Use the a=0.10 level of significance..

Average adult Americans are about one inch taller but nearly a whopping 25 pounds heavier than they were in 1960, according to a report from the Centers for Disease Control and Prevention (CDC). City A is considered one of America's healthiest cities. Is the weight gain since 1960 similar in city A? A sample of n=25 adults suggested a mean increase of 22 pounds with a standard deviation of 9.4 pounds. Is City A significantly different in terms of weight gain since 1960?
