Reading comprehension test scores of elementary school children randomly assigned to one of two teaching methods have the following summary statistics: # of Children Mean Standard Deviation Method 1 13 64 Method 2 13 69 8. We would like to conduct a hypothesis test to determine whether the true mean test score differs for the two teaching methods. Suppose that all necessary assumptions have been satisfied. What type of test should be used? pooled independent two-sample t test matched pairs t test unpooled (conservative) independent two-sample t test Reading comprehension test scores of elementary school children randomly assigned to one of two teaching methods have the following summary statistics: # of Children Mean Standard Deviation Method 1 13 64 Method 2 13 69 8.
