QUESTION 10 You hypothesize that drinking tea reduces stress levels so you design a study comparing stress levels between people who drink tea and people who do not drink tea. You collect data on 47 people and find that in your sample there are 21 people who do not drink tea and 26 people who drink drink tea. The mean stress score for non-tea drinkers is 76 with a standard deviation of 25, while the mean score for those who drink tea is 62 with a standard deviation of 13. Calculate the t-statistic. Use the t-test handout printout provided to calculate the t-statistic. Round to the nearest tenth. Enter the absolute value of your answer (l.e., do not include a negative sign if the answer is negative).
