Question 1081060: Find the P-value for the indicated hypothesis test. Round all proportions and standard scores to two decimal places.
A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 130 of the school's students, 30% of them plan to go into general practice. Find the P-value for a test of the school's claim.

z test
(phat-p)/SE
SE is sqrt (0.28*0.72/130) and that is 0.0394
0.02/0.0394=0.51, 1 way test
We would reject the Ho at at least the 0.25 level; the actual p-value is 0.31; so there is about 1/3 chance we would find a result this extreme or more if the true value were 0.28.
