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 x = 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. 13. What type of distribution is valid for this problem? Z- distribution (b) t-distribution, (c) F-distribution (d) Uniform distribution.
