Answer: (A) H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Step-by-step explanation:
Usually null hypothesis represents the claim that the values associated to the groups being tested have no statistical difference but alternative hypothesis supports the claim that there is statistical difference.
Let
be the population mean .
We are given that the mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle.
i.e. Null hypothesis :
Alternative hypothesis for two tail hypothesis has sign (≠).
i.e. Alternative hypothesis : 
∴ The hypotheses for a two-tailed test of the claimed potassium content:
H0: μ = 140 mg vs. H1: μ ≠ 140 mg
The answer is A: a slope of 2/9
First you need to change find the y-intercept by converting the standard form equation to slope-intercept form. The goal is to isolate y:
x + 4y = 12
x + 4y - x = 12 - x
4y = 12 - x
4y / 4 = 12/4 - x
y = 3 - x
Change so that the slope is before the intercept:
y = -x + 3
Now we know that the y-intercept is 3.
Use the slope equation, which is y2 - y1/x2 - x1, is find the slope:
5 - 3/9 - 0 = 2/9
So, the slope is 2/9!
