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. Use the chart on page 557 of your textbook to determine the critical value of t at a p = .05 level (two-tailed test). Enter this value exactly as it appears in the critical values of t chart (three decimals).
