What type of plot should we use to display this a. relationship? Circle all that apply. (A) Side-by-side dotplots (B) Segmented bar graph (C) Scatterplot (D) Side-by-side boxplots [3 pts] To what population can we generalize the results of this study? Circle one. (A) All MSU students (B) All MSU students who own parking permits (C) Only the students in the sample (D) All people who own parking permits b. 13 pts] The sample mean amount of time it took to find a parking spot was 6.2 minutes with a standard deviation of 2.71 minutes. Write a sentence interpreting this standard deviation in context of the problem. c. 3. Does Montana differ from the rest of the country in its preference for the Winter Olympics over the Summer Olympics?

2a) segmented bar graph and scatter plot .
2b) All MSU studentswho owns parking permits.
