I am studying reaction times in two different groups. The mean of group 1 is 100 milliseconds, the mean of group 2 is 102 milliseconds. The pooled standard deviation is 10 milliseconds. (1 pt) Question 1) What is the effect size of the difference? [remember, tell me how you're getting it...] (.5 pt) Question 2) Is this effect size small, medium, or large? (1 pt) Queston 3) I find that comparing these groups gives me a T statistic of 2. How many total subjects where there? (1 pt) Question 4) What is the null hypothesis for this comparison? Given the above (Q3), what is my decision regarding that null hypothesis? Bold-number your answers, each on a new line. Like: 1) answer 1 2) answer 2 etc
