Question
The body weight of a healthy 3-month-old colt should be about ? = 76 kg.
(a) If you want to set up a statistical test to challenge the claim that ? = 76 kg, what would you use for the null hypothesis
(b) In Nevada, there are many herds of wild horses. Suppose you want to test the claim that the average weight of a wild Nevada colt (3 months old) is less than 76 kg. What would you use for the alternate hypothesis
(c) Suppose you want to test the claim that the average weight of such a wild colt is greater than 76 kg. What would you use for the alternate hypothesis?
(d) Suppose you want to test the claim that the average weight of such a wild colt is different from 76 kg. What would you use for the alternate hypothesis?
(e) For each of the tests in parts (b), (c), and (d), respectively, would the area corresponding to the P-value be on the left, on the right, or on both sides of the mean?
H0?
? > 76 kg
? < 76 kg
? = 76 kg
? ≠ 76 kg
