14. An article, https://www.marketwatch.com/story/the-states-where-people-spend-the-most-on-lotto- tickets-2017-07-24, suggests residents of Massachusetts are tops in the U.S. for average amount spent on lottery tickets at $734.85 (What !?!). An analyst finds this suspicious and conducts his own survey of 30 Massachusetts' residents to determine if they spend less than this amount. The analyst's data showed a sample mean of $729.50 and sample standard deviation of $9.90. Use a significance level (a) of 1% to determine if the analyst's claim is supported. Use the p-value approach. (Remember population standard deviation is not known and need to use a t-distribution)
