It is known that the white shark grows to a mean length of 22 feet; however, one marine biologist believes that great white sharks off the Bermuda coast grow much longer. To test this claim, full-grown white sharks were captured, measured, and then set free. However, this was a difficult, costly and very dangerous task, so only four sharks were actually sampled. Their lengths were 20, 20, 24,and 21 feet. Do the data provide sufficient evidence to support the claim? Use ?=0.05

test statistic t=____.

rejection region t>____.
