2) Here are the heights of seven male giraffes (in m): 5.5 4.9 6.5 5.2 6.4 6.2 5.7 (a) Test Ho: u=5.842857. Use α = 0.05. (b) Repeat, but now test Ho: μ = 5.15. Again, use α = 0.05 (c) Finally repeat (b) except use a = 0.01. (d) What happened as you went from b to c (explain!). (e) As you make a smaller does it become easier or more difficult to reject Ho? Why? Make sure you understand this!
