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 of significance, is there evidence that the proportion of

males in this position at this medical center is different from what would be expected in the general workforce?

What are the correct hypotheses to test to determine if the proportion is different?

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

Calculate the test statistic.

ZSTAT

=

nothing

(Type an integer or a decimal. Round to two decimal places as needed.)

What is the p-value?

The p-value is

nothing

.

(Type an integer or a decimal. Round to three decimal places as needed.)

State the conclusion of the test.

Reject

Do not reject

the null hypothesis. There is

insufficient

sufficient

evidence to conclude that the proportion of

males in this position at this medical center is different from the proportion in the general workforce.
