Consider the plot provided in Q16.
Suppose the sample size is increased while the effect size and significance level remain unchanged. As a result, both sampling distributions become narrower, but their centres remain in the same locations. Based on the plot, what is the most likely consequence?

Question

Consider the plot provided in Q16.

Suppose the sample size is increased while the effect size and significance level remain unchanged. As a result, both sampling distributions become narrower, but their centres remain in the same locations. Based on the plot, what is the most likely consequence?

Answer

The red shaded area increases, the blue shaded area decreases, and statistical power increases.

Answer

The red shaded area remains equal to  α \alpha , the blue shaded area decreases, and statistical power increases.

Answer

Both shaded areas decrease because increasing the sample size reduces the probabilities of both Type I and Type II errors.

Answer

The red shaded area remains equal to  α \alpha , the blue shaded area increases, and statistical power decreases.

Answer

The blue shaded area decreases, but statistical power remains unchanged because the significance level has not changed.
