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

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.
