Question

3) The body weight of a healthy 3-month-old colt should be about $\mu = 60$ kg. a) You want to challenge the claim that $\mu = 60$ kg, Write the null and alternate hypotheses if you think the average weight is less than 60 kg: null: alternate: b) Using a sample of 100 colts you find that $\bar{x} = 58$ kg, with standard dev s = 8 kg. What distribution are you going to use? c) Degree of freedom df = d) Find the value of t: e) Find the P-value: f) Write your conclusion
