Question

A pilot study reports no relationship between miles run and HR in young athletes (r=0.7, p=0.06). If this study report is incorrect you know it is an example of:

	A violation of the normal distribution assumption
Select A dependent sample as your answer	A dependent sample
Select A type I error as your answer	A type I error
Select A type II error as your answer	A type II error

Answer 1

In statistical hypothesis testing a type I error is the rejection of a true null hypothesis, while a type II error is the non-rejection of a false null hypothesis.

Here it is mentioned that no relationship between miles run and HR in young athletes, which means we fail to reject the null hypothesis as hypothesis here is vs , as report is incorrect and we have fail to reject the null hypothesis which was suppose to be rejected,

Hence we have committed Type II error

So answer here is A type II error
