Acertain marathon has had a wheelchair division since 1977. an interested fan wondered what the difference in averaging winning times is between the women's wheelchair winner and the men's running winner. a 95% confidence interval for the difference in mean winning times (women's wheelchairminusmen's running) was calculated using the paired t-methods: (minus20,minus2) minutes. which of the following is the correct interpretation of this confidence interval? choose the correct answer below a. we are 95% confident that men's winning running times are between 2 and 20 minutes slower than women's winning wheelchair times, on average. b. we are 95% sure that the winning woman's wheelchair time is 2 to 20 minutes faster than the winning man's running time each year. c. we are 95% sure that 95% of the men have running times 2 to 20 minute faster than 95% of the women's wheelchair times. d. we are 95% confident that men's winning running times are between 2 and 20 minutes faster than women's winning wheelchair times, on average. e. the average women's winning wheelchair time is 2 to 20 minutes faster than the average men's winning running time 95% of the time.
