Correct Question:

David is a statistician. he has a sample size of 40 (which he cannot change). what element of his hypothesis test can he adjust to minimize the probability that he incorrectly rejects the null hypothesis?

a. the mean of the population

b. the mean of the sample

c. the standard deviation of the population

d. the significance level of the test

d. the significance level of the test

Step-by-step explanation:

The significance level of the test can be defined as the level of test where by the null hypothesis of a test is determined to be either true of false.

The significance level of test is represented alpha. It also shows us the probability that occurs when a null hypothesis is rejected, if it is true or false.

Significance level of test is used in a test that has a type 1 error.
