Answer #1

It is example of type II error.

The following is the definition of type I and

type II error for your clarification.

type I error is the rejection of a true null hypothesis (also known as a "false positive" finding or conclusion), while a type II error is the non-rejection of a false null hypothesis (also known as a "false negative" finding or conclusion).

Here our null hypothesis is fail to reject and

Actually the reality is not.

So your answer is type II error.

    You are asked to conduct a simulation and run a hypothesis test at a significance level of 0.10. Based on your simulation, you find that the p-value is 0.051. What does this mean for your hypothesis test? 1. Since the p-value is greater than the significance level, you must fail to reject the null hypothesis. 2. Since the p-value is less than the significance level, you must fail to reject the null hypothesis. 3. Since the p-value is less than...
