Question:

a. The file MedSalaries is a random sample of salaries of medical doctors who were teaching at United States universities in 2009. Create a bootstrap of the median by taking 1000 resamples (with replacement). Describe the shape of the bootstrap Is it appropriate to create a bootstrap t confidence interval or a bootstrap percentile confidence interval for the median?
b. Create a bootstrap of the 25% trimmed mean by taking 1000 resamples (with replacement). In other words, calculate the mean of the middle 50 observations from each resample. Describe the shape of the bootstrap Is it appropriate to create a bootstrap t confidence interval or a bootstrap percentile confidence interval for the 25% trimmed mean?
c. Create a bootstrap of the 5% trimmed mean by taking 1000 resamples (with replacement). In other words, calculate the mean of the middle 90 observations from each resample. Describe the shape of the bootstrap Is it appropriate to create a bootstrap t confidence interval or a bootstrap percentile confidence interval for the 5% trimmed mean?
d. Calculate a bootstrap t confidence interval and bootstrap percentile confidence interval for each of the preceding parts of this exercise if the bootstrap indicates that it is appropriate.
