Plug the y value in for y and plug the x value in for x
> less than
<u>></u> less than or equal to
Example:
(4,5)
y > 5y <u>></u> x
5 > 5x5 <u>></u> 4 = 5 > 25 <u>></u> 4 = false
they all should be false
if one had to be correct, I would say (0, 0)

Answer:
CI = 29.8 ± 3.53
Critical value is z = 2.58
Step-by-step explanation:
First of all let's find margin of error. It is given by the formula;
ME = zσ/√n
We are given;
Standard deviation; σ = 3.62
Sample size; n = 7
Mean; x¯ = 29.8
Now, z-value for 99% Confidence level is 2.58
Thus;
ME = (2.58 × 3.62)/√7
ME = 3.53
CI is written as;
CI = x¯ ± ME
CI = 29.8 ± 3.53
Critical value is z = 2.58
They ate 2/3 together. And, they have 1/3 left!
