Question: In a random sample of 1200 college students 800 of them declared that they are conscious of good exercising habits since attending college. A pervious national survey has revealed that about 55% of high schools feel that they too are conscious of good exercising habits.

• If the true population of college students who have good exercising habits is to be estimated with 94% confidence and accurate to within .001. How many college students should be sampled?
