QUESTION 11 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. Above you have calculate the t-statistic and found the critical value of t. Based on this information, which of the follow statements is correct? O you accept the null hypothesis because your calculated t-statistic value is greater than the critical value of t O you reject the null hypothesis because your calculated t-statistic value is greater than the critical value of t O you accept the null hypothesis because your calculated t-statistic value is less than than the critical value of t O you accept the null hypothesis because your calculated t-statistic value is less than than the critical value of t
