A car dealer randomly selects 24 automatic cars and 21 manual cars to compare the fuel efficiency of the engines. A dotplot of the data is shown below, where each dot represents the fuel efficiency of one car (km/l) in the sample (greater fuel efficiency is indicated by larger numbers). Choose TWO options that best describes what the graph tell you about the fuel efficiency of the cars in the sample: a) fuel efficiency for manual cars is positively skewed. b) manual cars have the higher median fuel efficiency. c) the least fuel efficient car in the sample is manual. d) the most fuel efficient car in the sample is automatic. e) automatic have the larger range. d) fuel efficiency for manual cars is negatively skewed.

A researcher is investigating the physical characteristics that influence whether a person's face is judged as beautiful. The researcher selects a photograph of a woman and then creates two modifications of the photo by (1) moving the eyes slightly farther apart and (2) moving the eyes slightly closer together. The original photograph and the two modifications are then shown to a sample of n = 150 college students, and each student is asked to select the "most beautiful" of the three faces. The distribution of responses was as follows: Original Photo Eyes Moved Apart Eyes Moved Together 51 72 27 Do the data indicate any significant preferences among the three versions of the photograph?

A state fisheries commission wants to estimate the number of bass caught in a given lake during a season in order to restock the lake with the appropriate number of young fish. The commission could get a fairly accurate assessment of the seasonal catch by extensive “netting sweeps" of the lake before and after a season, but this technique is much too expensive to be done routinely. Therefore, the commission samples a number of lakes and record the seasonal catch (thousands of bass per square mile of lake area) and size of lake (square miles). A simple linear regression was performed and the following R output obtained. Estimate Std.
