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. 14. What conditions are required to find a confidence interval for the population mean lifetime? (a) o is unknown (b) The population is normally distributed (c) np ≥ 10, nq ≥ 10 (d) because of (a) and (b)
