Suppose that a travel bureau claims that the trees in a forest are 85 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?

Step-by-step explanation:

It is given that Suppose that a travel bureau claims that the trees in a forest are 85 feet tall on average, with a standard deviation of 0.2 feet.

Here, Mean=85, Standard deviation=0.2, Sample=64.

Now, using the confidence interval as 95%, then z=1.96.

Thus, Margin error is given as:

Therefore, confidence interval:

that is:

Mean heights outside the confidence interval will be:

and .

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
