Mathematics: According to the most recent data, 12.3% of engineers (electrical, mechanical, civil, and industrial) were women. suppose a random sample of 80 engineers is selected. a. how likely is it that a random sample of 80 people will contain 12 or more women in these positions? b. how likely is it that the random sample will contain fewer than 5 women in these positions? c. if the random sample included 160 engineers, how would this change your answer to part b?

Step-by-step explanation:

Given that according to the most recent data, 12.3% of engineers (electrical, mechanical, civil, and industrial) were women.

n =80

p is normal with p = 12.3% and std error = $\sqrt{\frac{0.123(0.877}{80} } =0.03672$

Prob 12 or more women = P(p>0.15)

=P(Z> $\frac{0.15-0.123}{0.03672} =0.74)$

=0.5-0.2704=0.2296
