Answer:
Step-by-step explanation:
The null hypothesis is usually the default statement while the alternative hypothesis is its opposite and usually tested against the null hypothesis.
In this case study, the null hypothesis is u = 21%/0.21, the percentage is not different among residents in Sonoma County and is equal to 0.21.
While the alternative hypothesis is u =/ 0.21, the percentage is different among residents in Sonoma County; not equal to 0.21
Answer:
27.5 /100 are running for a cause
Step-by-step explanation:
We know that 220/800 are running for a cause
Divide the top and bottom by 8 to get the fraction out of 100
220 /8 =27.5
800/8 = 100
27.5 /100 are running for a cause
2) $3.85

<span>Y=2/3x+3 so slope = 2/3
</span><span>2x-3y=8
3y = 2x - 8
y = 2/3x - 8/3 so slope = 2/3
both equations have same slope = 2/3
so answer: </span><span>parallel</span>
