The Department of Education Would Like to Test the Hypothesis

question 32

Multiple Choice

The Department of Education would like to test the hypothesis that the average debt load of graduating students with a Bachelor's degree is equal to $17,000. A random sample of 34 students had an average debt load of $18,200. It is believed that the population standard deviation for student debt load is $4,200. The Department of Education would like to set α = 0.05. The conclusion for this hypothesis test would be that because the absolute value of the test statistic is______

• A)less than the absolute value of the critical value, we cannot conclude that the average student debt load is not equal to $17,000.
• B)more than the absolute value of the critical value, we can conclude that the average student debt load is not equal to $17,000.
• C)more than the absolute value of the critical value, we cannot conclude that the average student debt load is not equal to $17,000.
• D)less than the absolute value of the critical value, we can conclude that the average student debt load is not equal to $17,000.

Definitions:

Level Of Significance

The probability of rejecting the null hypothesis when it is actually true, often denoted by alpha (α).

Null Hypothesis

A default hypothesis that there is no significant difference or effect, tested against the alternative hypothesis.

Critical Value

A point on the scale of the test statistic beyond which we reject the null hypothesis; it depends on the chosen level of significance.
