Recently, a large academic medical center determined that 12 of 23 employees in a particular position were male, whereas 57% of the employees for this position in the general workforce were male. At the 0.05 level ofsignificance, is there evidence that the proportion of males in this position at this medical center is different from what would be expected in the generalworkforce?

What are the correct hypotheses to test to determine if the proportion isdifferent?

A.

H0: 0.57; H1: =0.57

B.

H0: 0.57; H1: <0.57

C.

H0: =0.57; H1: 0.57

D.

H0: 0.57; H1: >0.57
