A) Option - B) H0: = 0.42
H1: 0.42
B) = 15/24 = 0.625
The test statistic z = ( - )/sqrt((1 - )/n)
= (0.625 - 0.42)/sqrt(0.42 * (1 - 0.42)/24)
= 2.03
C) P-value = 2 * P(Z > 2.03)
= 2 * (1 - P(Z < 2.03))
= 2 * (1 - 0.9788)
= 2 * 0.0212
= 0.0424
As the P-value is less than the signifiance level (0.0424 < 0.05), we should reject the null hypothesis.
At 0.05 significance level, there is sufficient evidence to support the claim that the proportion of males in this position at this medical center is different from what would be expected in the general workforce.

Recently, a large academic medical center determined that 11 of 17 employees in a particular position were male, whereas 41% of the employees for this position in the general workforce were male. At the 0.01 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? a. What are the correct hypotheses to test to determine if the proportion is different? b....

Recently, a large academic medical center determined that 9 of 15 employees in a particular position were female, whereas 49% of the employees for this position in the general workforce were female. At the 0.05 level of significance, is there evidence that the proportion of females 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 ifferent? 0.60 a...
