For this problem, carry at least four digits after the decimal
in your calculations. Answers may vary slightly due to
rounding.
In a survey of 1000 large corporations, 246 said that, given a
choice between a job candidate who smokes and an equally qualified
nonsmoker, the nonsmoker would get the job.
(a) Let p represent the proportion of all corporations
preferring a nonsmoking candidate. Find a point estimate for
p. (Round your answer to four decimal places.)
(b) Find a 0.95 confidence interval for p. (Round your
answers to three decimal places.)
A random sample of 328 medical doctors showed that 166 had a solo practice. (a) Let p represent the proportion of all medical
doctors who have a solo practice. Find a point estimate for
p. (Use 3 decimal places.)
Give a brief explanation of the meaning of the interval. 95% of the confidence intervals created using this method would include the true proportion of physicians with solo practices.95% of the all confidence intervals would include the true proportion of physicians with solo practices. 5% of the confidence intervals created using this method would include the true proportion of physicians with solo practices.5% of the all confidence intervals would include the true proportion of physicians with solo practices.

(c) As a news writer, how would you report the survey results
regarding the proportion of corporations that would hire the
equally qualified nonsmoker?
