A recent newspaper article claims that teens send more than 82.2 text messages per day. A study is conducted and 25 randomly selected teens are selected and the mean number of text messages is 86.1 with a standard deviation of 8.4. Test the newspaper's claim at the 0.01 significance level. You believe the population is normally distributed. H.:µ = 82.2 Ha:µ > 82.2 a. What is the test statistic? (Report answer accurate to four decimal places.) test statistic = b. What is the p-value? (Report answer accurate to four decimal places.) p-value = c. The p-value is greater than a less than (or equal to) a
