QUESTION 10 You hypothesize that drinking water increases test scores so you design a study comparing test scores between people who drink water and people who do not drink water.You collect data on 62 people and find that in your sample there are 27 people who do not drink water and 35 people who drink water. The mean test score for non-water drinkers is 62 with a standard deviation of 13, while the mean score for those who drink water is 75 with 11 standard deviation. Calculate the t-statistic. Use the t-test handout printout provided to calculate the t-statistic. Show your work. Round to the nearest tenth. Enter the absolute value of your answer (I.e., do not include a negative sign if the answer is negative).
