Using the Heart Rate Dataset, how can I test for a significant difference between the average resting heart rate for males and the average heart rate of females by comparing the two confidence intervals or by running a two-sample test with unequal variances. How can I tell if the values are significant or not and what would be the null hypotheses being tested ?
