3.To obtain an estimate of the proportion of 'full time' university students who have a part time job in excess of 20 hours per week, the student union decides to interview a random sample of full time students. They want the length of their 95% confidence interval to be no greater than 0.1. and assume variance is equal to 4. What size sample, n should be taken?

15) The Carolina Tobacco Company advertises that its best selling cigarette contain at most 40 mg of nicotine, but Consumer Advocate magazine conducts tests of 10 randomly selected cigarettes and find that x−=43.3 mg and s=3.8mg. Other evidence suggests that the distribution of nicotine content is a normal distribution. With a significance level of ∝ =0.01 in testing the company’s claim that the mean nicotine content is at most 40mg.
