Question 26 True or False? The lower a p-value is, the more it suggests that the results of a hypothesis test are statistically significant. True B False
Question 27 in a study of 50 sets of identical twins, one twin within each pair is assigned to do cardio exercise, and the other twin is assigned to do no exercise. After several months, their resting heart rate is recorded. True or false? The two samples in this study (Cardio and no exercise) are independent True False
Question 28 In a study of 50 sets of identical twins, one twin within each pair is assigned to do cardio exercise, and the other twin is assigned to do no exercise. After several months, their resting heart rate is recorded. The difference in heart rates for each set of twins is calculated as follows: Cardio Heart Rate - No Exercise Heart Rate. The mean difference is found to be - 1.2 beats per minute (bpm) with a standard deviation of 0.15 bpm. Calculate and interpret a 95% confidence interval for the mean difference in resting heart rates, (-1.243, -1.157) For people who do cardio exercise, on average their resting heart rate is between 1.157 and 1.243 bpm lower than the resting heart rate for people who do not exercise. B (-1.23,-1.17) For people who do cardio exercise, on average, their resting heart rate is between 1.17 and 1.23 bpm lower than the resting heart rate for people who do not exercise. (-1.23,-1.17) For people who do cardio exercise, on average, their resting heart rate is between 1.17 and 1.23 bpm higher than the resting heart rate for people who do not exercise (-1.243,-1.157) For people who do cardio exercise, on average, their resting heart rate is between 1.157 and 1.243 bpm higher than the resting heart rate for people who do not exercise,
