Answer:
Step-by-step explanation:
Given that a part of a study of the treatment of anemia in cattle, researchers measured the concentration of selenium in the blood of 36 cows who had been given a dietary supplement of selenium (2 mg/day) for one year.
If x is the selenium concentration then
X has mean= 6.21 mg/dl
and std dev = 1.84
Sample size n = 36
std error of sample = 
Margin of error for 95%
Confidence interval = 
When graphing, its how much you rise and run
thats the formula when u have a graph and the question is asking for the slope.
you chose a point, and go down or up however many times it goes to the next point, and you run to the left however many times it gets you to get to that point.
if the line goes downward the slope is therefore negative, and if the line goes upward, the slope is therefore, positive.
m in math is meant to be slope, so
X should equal 11
2(3)2-1
6(2)-1
12-1
11
