11-15 A veterinarian collects data on the number of times race horses are raced during their career. The researcher finds the average number of races a horse enters is = 15.3 with a standard deviation of s = 6.8 in a sample of n = 20 horses. Suppose the number of times horses are raced follows a normal distribution. 15. Suppose a confidence interval is to be constructed to estimate the mean time all horses are raced. The margin of error for a 99% confidence interval is given by (rounded to three digits) a. 4.350. b. 1.560. C. 0.340. d. 0.358.
