Answer:
The mean blood cholesterol level for the sample is 184mg/dl
Step-by-step explanation:
Hello!
When you construct any confidence interval for the mean, the general structure is "estimator±margin of error"
For example under a Z-distribution the formula is
X[bar]±
*(σ/√n)
So you subtract or add "
*(σ/√n)" to the sample mean. In other words, this type of confidence interval is centered on the sample mean.
If the interval is already calculated, you just have to add both limits and divide by two to get the sample mean.
[166mg/dl;202mg/dl]
sample mean: x[bar]= (166+202) = 184mg/dl

I hope you have a SUPER day!
we have that
1) Relationship B has a lesser rate than Relationship A
2) The graph represents Relationship A
we know that
The rate is equal to the slope of the linear equation in the graph
Step 1
<u>Find the slope of the Relationship A</u>
we have

we know that
The formula to find the slope m between two points is equal to

substitute the values



Step 2
<u>Find the equation that could represent Relationship B</u>
we know that
Relationship B has a lesser rate than Relationship A
so
the slope of the Relationship B is less to the slope of the Relationship A

therefore
<u>the answer is</u>
------> because the slope is 
------> because the slope is
