Question

A coach claims that the population average resting pulse rate of football players is 50 beats per minute. In order to determine if this claim is correct or not, a sample of 100 football players was selected. The sample showed a sample mean resting pulse rate of 52.5 beats per minute. Is the coach's claim correct?

1) Yes
2) No

Answer 1

The coach's claim that the average resting pulse rate for football players is 50 beats per minute is challenged by a sample mean of 52.5 beats per minute. Statistical testing is needed to confirm the discrepancy.

Step-by-step explanation:

Based on the sample mean resting pulse rate of 52.5 beats per minute from a sample of 100 football players, which is higher than the coach's claim of a population average of 50 beats per minute, it suggests that the coach's claim may not be correct. However, to definitively determine if the coach's claim is incorrect, a statistical test should be performed to assess if the difference between the sample mean and the claimed population mean is statistically significant.
