question 117

Multiple Choice

Consider the following printout. HYPOTHESIS: VARIANCE $X = x$
$$X = \text { gpa }$$
SAMPLE MEAN OF $\mathrm { X } = 2.8814$
SAMPLE VARIANCE OF $X = .21000$
SAMPLE SIZE OF $X = 250$
HYPOTHESIZED VALUE $( \mathrm { x } ) = 3.0$
VARIANCE $\mathrm { X } - \mathrm { x } = - .1186$
$$z = - 4.09209$$
Is this a large enough sample for this analysis to work?

• A) Yes, since the population of GPA scores is approximately normally distributed.
• B) Yes, since the \(n p > 15\) and \(n q > 15\).
• C) Yes, since \(n = 250\), which is greater than 30 .
• D) No.
