A report says that high school boys score better in science than the high school girls. 12 high school female students and 12 high school male students are randomly selected and their science scores are given below. Find out if the report is correct at 0.05 level of significance. Assume equal variances of the population. Girls 70 79 77 72 74 79 71 76 79 71 72 75 Boys 78 77 86 81 75 81 82 90 84 80 81 89 A. What is the value of degrees of freedom? B. What is the value of test statistic? C. The critical region is greater than D. The p-value is E. The decision is Round off to 3 decimal places Round off to 3 decimal places Round off to 3 decimal places H. (Type "Reject" or "Fail to Reject")
