Consider the Following Printout $\mathrm { X } = \mathrm { x }$

Multiple Choice

Consider the following printout. HYPOTHESIS: VARIANCE $\mathrm { X } = \mathrm { x }$
$$X = \text { gpa }$$

$$\begin{aligned}\text { SAMPLE MEAN OF X \( =2.2911 \) }\\\text { SAMPLE VARIANCE OF X \( =.18000 \) }\\\text { SAMPLE SIZE OF X \( =199 \) }\\\text { HYPOTHESIZED VALUE \( (x) =2.4 \) }\\\\\text { VARIANCE } X - x & = - .1089 \\z & = - 3.62091\end{aligned}$$ Suppose we tested Ha: ? < 2.4. Find the appropriate rejection region if we used ? = .05.

A) Reject if z < -1.645.
B) Reject if z > 1.645 or z < -1.645.
C) Reject if z > 1.96 or z < -1.96.
D) Reject if z < -1.96.
