Question

If the critical z-value for a hypothesis test equals 2.45, what value of the test statistic would provide the least chance of making a Type I error?

Multiple Choice

• 4.56

• 2.46

• 2.45

• 3.74

Answer 1

Type I error

If we reject the null hypothesis but it is true then the type I error is happen.

Here critical value is 2.45

So we reject the null hypothesis if the  test statistic value is more than 2.45

If the test statistic value is much larger than 2.45 then we are more confidently reject the null hypothesis. And so the chance of type I error also minimize for large test statistic value.

So correct choice is that 4.56

because it is largest than the others.
