Refer to the data on sanitation levels of cruise ships, Exercise 2.17.
a. Use the box plot method to detect any outliers in the data.
b. Use the z-score method to detect any outliers in the data.
c. Do the two methods agree? If not, explain why.

Data from Exercise 2.17

An experiment was conducted to characterize sound waves in a spherical cavity. American Journal of Physics, June , 2010.) A fully inflated basketball, hanging from rubber bands, was struck with a metal rod, producing a series of metallic sounding pings. Of particular interest were the frequencies of sound waves resulting from the first 24 resonances (echoes). A mathematical formula, well known in physics, was used to compute the theoretical frequencies
