Question

The following list shows three factors that can either increase or decrease the probability of a Type II error.

The sample size is increased.
The significance level is increased.
The standard error is increased.
Which factors alone will cause the probability of a Type II error to increase?

A
I only

B
II only

C
III only

D
I and II only

E
I, II, and III

Answer 1

Answer:

C) III only

Step-by-step explanation:

An increase in standard error increases variability of the sampling distribution. Due to the increase in variability of the sampling distribution, it is more difficult to detect a true difference, and the probability of a Type II error is increased.
