Question
degree, ultimately receiving either an M.S. or An article in Fortune (september 21, 1992) claimed that nearly one-half of all engineers continue academic studies beyond the B.5. d 484 new engineering graduates were planning graduate study Are the data from Engineering Horlzons consistent with the claim reported by Fortune? Use a 0.10 in reaching your conclusions. Find the P-value Give your answer The true proportion of engineering students planring graduate studies a ph.D. dagree. Data from an article in Engineering Horizons (Spring 199D) indicated that 117 of Engineering Horizons (Spring 1990) indicated significantly different from 0.5 at o-0.10 0.005 The P-value is less than choose the least possible)Explanation / Answer
Ans:
Given that
sample proportion=117/484=0.242
population proportion=0.5
standard deviation=sqrt(0.5*(1-0.5)/484)=0.023
Test statistic:
z=(0.242-0.5)/0.023=-11.36
p-value(2 tailed)=0 approximately
As,p-value<0.1,we reject null hypothesis.
The true proportion of engineering students planning graduate studies is significantly different from 0.5.
