Complete 12 pages APA formatted article: Statistics: Population Distributions. The experts in the field8 as have also emphasized that individuals who are physically fit have a higher stroke volume as compared to inactive individuals. This means that individuals having a poor physical condition will reach their maximum heartbeat rate at a lower work level than individuals who are physically fit. Based on the above belief, a theory has been put forward that since physically fit individuals have a higher aerobic capacity before reaching maximum heart rate, therefore, they will have a slower rate of increase in heartbeat and a faster return to the resting return after the exercise.
For the verification of aforementioned hypothesis, a controlled experiment will be conducted in which the subject’s heart rate before exercise and 15 minutes after exercise and then 30 minutes after exercise will be measured to know whether there are significant differences in the heart rate of individuals in the group.
The data for the given variable is spread symmetrically around the central location. It has a modal class. I expect the data to be modal since most of the individuals will have a common heartbeat rate with a few exceptional cases. My expectations are supported by the graph of the histogram as the majority of the frequency of the data lies in the middle of the set.
The value of t-test statistic is -0.339 and it does not fall in the rejection region thus we do not reject the null hypothesis. The test results are not statistically significant at the 5% level. that is, at the 5% significance level, the data do not provide sufficient evidence to conclude that there is the difference in the mean heart rate of the tall and short individuals. .
