Answer: False.

The sample mean does not determine how wide the confidence interval would be. The sample mean determines the center of the confidence interval. The confidence level, standard deviation, and the sample size would determine the confidence interval width.

If the domain of a function that is translated down 3 is (0, 4), (-5, 8), (4, -2), what is the range?
olga55 [171]

Given:

The domain of function that is translated down 3 is (0, 4), (-5, 8), (4, -2).

To find:

The range of the function.

Solution:

If a function is translated 3 units down, then

(x,y)\to (x,y-3)

Using this rule, we get

(0,4)\to (0,4-3)

(0,4)\to (0,1)

Similarly,

(-5,8)\to (-5,5)

(4,-2)\to (4,-5)

The range of the given function is (0, 1), (-5, 5), (4, -5).

Therefore, the correct option is A.
