A statistics instructor claims that statistical knowledge causes an increase in life satisfaction. They want to test this experimentally by randomly assigning 39 students to receive additional statistics education and then assessing life satisfaction to find a mean o and a standard deviation of 23. Another 89 students receive no additional statistic education and are assessed on their life satisfaction to find a mean of 52 and a star deviation of 18. They plan to assess the difference using mu1 - mu2, where 1 mu1 Additional statistics education and 12 mu2 = No additional statistics education Please compute your t-statistics and report to 4 decimal places.
