question 53

Multiple Choice

In 1990, the average math SAT score for students at one school was 495. Five years later, a teacher wants to perform a hypothesis test to determine whether the average SAT score of students at the
School has changed from the 1990 mean of 495. The hypotheses are: $$\begin{array} { l } \mathrm { H } _ { 0 } : \mu = 495 \\\mathrm { H } _ { \mathrm { a } } : \mu \neq 495\end{array}$$
Explain the meaning of a Type II error.

• A) Concluding that \(\mu \neq 495\) minutes when in fact \(\mu = 495\)
• B) Failing to reject the hypothesis that \(\mu = 495\) when in fact \(\mu = 495\)
• C) Failing to reject the hypothesis that \(\mu = 495\) when in fact \(\mu \neq 495\)
• D) Concluding that \(\mu > 495\) when in fact \(\mu = 495\)
