a. From the first student's data, what percentage of men used turn signals, and what percentage of women used them? of men used turn signals, and of women used them.

(Round to one decimal place as needed.)

b. From the first student's data, assuming the conditions are met (although admittedly this was not a random selection), find a 95% confidence interval for the difference in percentages (men−women).State whether the interval captures 0, and explain whether this provides evidence that the proportions of men and women who use signals differ in the population.

The 95%confidence interval for the difference in percentages (men−women) is (. %. %)

(Round to one decimal place as needed.)

c. From the second student's data, first find the percentage of men and the percentage of women who used turn signals, and then, assuming the conditions are met, find a 95% confidence interval for the difference in percentages. State whether the interval captures 0, and explain whether this provides evidence that the percentage of men who use turn signals differs from the percentage of women who do so.

c. % of men used turn signals, and. %. of women used them.

(Round to one decimal place as needed.)

The 95% confidence interval for the difference (men−women) is negative %,%.
