A hospital recruiting company for doctors is conducting a study to determine whether the average doctor's salary (in thousands of dollars) is significantly more than $89 thousand dollars. A random sample of 27 doctors' salaries (in thousands of dollars) is given in the table. Test the hospital recruiting company's claim using a 5% level of significance. Salary (in thousands of dollars) 92.06 94.94 99.45 98.39 94.83 100.11 92.84 85.74 99.71 96.57 91.02 98.14 89.45 91.11 103.42 83.71 84.71 84.08 89.19 95.78 87.47 80.08 86.6 105.23 90.52 100.1 94.73 Preliminary: a. Is it safe to assume that n 5% of all doctors earning a salary? O Yes O No b. Is n 2 30? O Yes O No c. Since n < 30 , then determine whether the box plot of salaries contains any outliers. 80 85 90 95 100 105 110 Salary O There are outliers from the box plot. O There aren't outliers from the box plot. Note: Without being given that the population is normally distributed, and given a sample less than 30, we are required to verify that there are no outliers by plotting a box plot and a normal probability plot.

Statistics Canada conducts an annual survey to estimate the proportion of Canadians aged 20 - 24 years of age who are smokers. The most recent application of the Canadian Tobacco Monitoring Survey involved a random sample of n=496 Canadians aged 20 to 24 years of age. Each was asked for the smoking status. The number of 20 to 24 year-olds sampled who indicated they were smokers was 333.(a) Compute the sample proportion. Use at least four decimals in your answer.p^= __________ (b) Using your answer in (a), find a 97% confidence interval for pnow, the current proportion of 20 to 24 year old Canadians who are smokers, by Bootstrapping 1000 samples. Use the seed 3994 to ensure that R-Studio "randomly" samples the same "random" samples as this question will expect.You can do this by including the code, you can copy it into your R-Studio to bootstrap your samples.RNGkind(sample.kind = "Rejection");set.seed(3994);B=do(1000) * mean(resample(c(rep(1,333),rep(0,496-333)), 496));Use at least four…
