QUESTION 8 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. Use the chart on page 557 of your textbook to determine the critica 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).
