Please help by explaining the concepts underlying how the following problems is solved

Question 4 of 23\A study of the effects of exercise used rats bred to have high or low capacity for exercise . The eight high - capacity rats hadmean blood pressure 89 millimeters of mercury ( mm He ) and standard deviation 9 mm He ; the eight low- capacity rats hadmean blood pressure 105 mm He with standard deviation 13 mm He .We suspect that rats with a low capacity for exercise tend to have a higher blood pressure than rats with high capacity forexercise . To see if this is true , we want to test the hypotheses for the mean blood pressure of all rats with high capacity ( HC )for exercise and all rats with low capacity ( [ C ) for exercise .Select the correct null and alternative hypotheses for the test .O HO : MHC = MIC Versus Ha: MHC < MIC .O HO : MHC = MIC Versus Ha : HHC * MIC.O HO : MHC = 89; MIC = 105 versus Ha : MHC * 89; MIC $ 105 .O HO : MHC = 9; MIC = 13 versus Ha : MHC * 9; MLC $ 13 .
