a study of the effects of exercis used rats bred to have high or low capacity for exercise. The 8 high capacity rats had mean blood pressure 89 mm Hg and variance 81; the 8 low-capacity rats had mean blood pressure 105 mm Hg with variance 169. What is the value of the two-sample t statistic for comapring the two population means

Step-by-step explanation:

From the question we are told that:

Sample 1

Sample 1 mean blood pressure

Sample 1 variance

Sample 2

Sample 2 mean blood pressure

Sample 2 variance

Generally the equation for the test of statistic is mathematically given by

therefore the samples test for comparing the two population means

because its not ur topic and its not for is for homework not that.
