Consider the Following Printout $X = x$ $$X = \text { gpa }$$

question 128

Multiple Choice

Consider the following printout.
HYPOTHESIS: VARIANCE $X = x$
$$X = \text { gpa }$$
SAMPLE MEAN OF $X = 2.5516$
SAMPLE VARIANCE OF X $= .24000$
SAMPLE SIZE OF $X = 157$
HYPOTHESIZED VALUE $( x ) = 2.7$
VARIANCE $X - x = - .1484$
$$z = - 3.79558$$
Is this a large enough sample for this analysis to work?

• A) Yes, since the \(n p > 15\) and \(n q > 15\).
• B) Yes, since \(n = 157\), which is greater than 30 .
• C) No.
• D) Yes, since the population of GPA scores is approximately normally distributed.
