Question 967077: Suppose that a travel bureau claims that the trees in a forest are 83 feet tall on average, with a standard deviation of 2 feet. If you took a sample of 64 trees, which of the following mean heights would be outside the 95% confidence interval? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Suppose that a travel bureau claims that the trees in a forest are 83 feet tall on average, with a standard deviation of 2 feet. If you took a sample of 64 trees, which of the following mean heights would be outside the 95% confidence interval?
--------
Form the 95% CI::
sample mean = 83
Error Margin = 1.96*2/sqrt(64) = 0.49
-----
95% CI:: 83-0.49 < u < 83+0.49
-----
Comment:: No mean heights were listed in your post.
