Question

A ________ is a numerical quantity computed from the data of a sample and is used in reaching a decision on whether or not to reject the null hypothesis.
a. significance level
b. critical value
c. test statistic
d. parameter

Answer 1

The answer for the completion exercise shown above is the second option (option b), which is:

 b. critical value.

 Therefore, you have that the text is: "A critical value is a numerical quantity computed from the data of a sample..."

 This numeral quantity is used in statitics. Then, if the absolute value is greater that the quantity defined before, the null hypothesis must be rejected.
