Facebook Friends Many people believe that the average number of Facebook friends is 140. The population standard deviation is 36.9. A random sample of 38 high school students in a particular county revealed that the average number of Facebook friends was 146. At α=0.01, is there sufficient evidence to conclude that the mean number of friends is greater than 140? Use the P-value method. Use a graphing calculator. Find the P-value. Round the answer to at least four decimal places. P-value=
