Suppose that a travel bureau claims that the trees in a forest or 84 feet tall on average, with a standard deviation of 0.2 feet. if you took a sample of 64 trees, which of the following mean heights would be outside the 95% confidence interval?

 

The solution would be like this for this specific problem: mean = 84, SD = 2, Sample 64,  95% confidence interval: z = 1.96

ME = 1.96*2/√64 = .49  Using .5

CI: 83.5< mean < 84.5

Outside of that:  x ≤ 83.5  and ≥  84.5

I hope this helps and if you have any further questions, please don’t hesitate to ask again.

What are the following algebraic equations. you need to post those if you want the answer
