Question

Many primary care doctors feel overworked and burdened by potential lawsuits. In fact, a goupot researchers reponed that 63 i of al general practice physicians do not recommend medicine as a career Letxrepresent the number of sampled 9eneral practice physicians who do not recommend medicine as a career Complete pats a through d a. Explain why xis approximately a binomial random variable. O A. The experiment consists of nidentical dependent trials, with more than two possible outcomes The probabiltythat an eventoccurs varies from trial to tial O B. The experiment consists of n identical independent trals, where there are only two possible outcomes Sfor success) and F (Tor Falue) The probability of S varies from trial to trial. The valablexis the number of F's O C. The experiment consists of n identical dependent trials, where there are only tro possible outcomes, S (for Success) and F (for Falune) O D. The experiment consists of nidentical independent tials, where there are only two possible outcomes, S (for Success) and F (for Falune) The probability of S remains the same from trial to trial. The variablexis the number of S's inntrals. b. Use the researchers' report to estimate p for the binomial random variable. p Type an integer or a decimal) c. Consider a random sample of 23 general practice physicians. Use p from partb to find the mean and standard daviation of the number who do not recommend medicine as a career w. Round to two decimal places as needed) o Round to three decimal places as needed d. For the sample of part c find the probability that at least one general practice physician does not recommend medicine as a Activate Windows Click to select your answer(s)

Explanation / Answer

a) option D is correct

b) p=0.63

c) mean =np=14.49

std deviation=(np(1-p))1/2 =2.315

d)probability =1-P(everybody recommend) =1-(1-0.63)23 =1-0.0000=~1
