A 95% confidence interval for the difference of the mean number of times race horses are lame and the number of times horses used for jumping are lame over a 12-month period [μ (race) – μ (jump)] is calculated to be (–2.13, 3.47). Therefore, it can be concluded that:A 95% confidence interval for the difference of the mean number of times race horses are lame and the number of times horses used for jumping are lame over a 12-month period [μ (race) – μ (jump)] is calculated to be (–2.13, 3.47).
