in order to evaluate two methods of teaching statistics students were randomly assigned to two groups. In group one example of 32 students were taught using method A, and in group 2 a sample of 36 students were taught using method B. At the end of the instructional methods, both groups were given the same achievement test. For group one the average test score was 87.67 with a standard deviation of 3.72. For group to the average test score was 89.29 with a standard deviation of 3.77. Test at a 10% significance level with the test scores differs for the two groups. Calculate the test statistic and rounded of to three decimals
