The resting heart rate for healthy adult horses are normally distributed with an average of 46 beats per minute with a standard deviation of 8 beats per minute. A horse whose resting heart rate is in the upper 10% of the distribution of heart rates may have a secondary infection or illness that needs to be treated. How fast must a healthy horse’sheart be beating to fall into this at-risk group?

In this assignment, you will test for a significant difference between the average resting heart rate of males and the average resting heart rate of females in your heart rate data. You have observed that the mean rates are not exactly the same but are they significantly different? You may use either of the two methods for testing a hypothesis illustrated in Realizeit: compare the two confidence intervals or use the data analysis tool to run a two-sample test with...
