Answer:
Horizontal line (0 slope)
Step-by-step explanation:
The equation is , so you'd just insert what you know.
It would look like this: .
We would solve. 6-6=0, while 4-(-2)=6.
So, we have 0/6, which gives you 0, and it would be a horizontal line, since a horizontal line is portrayed by 0 slope.
<h2><u>Answer with explanation:</u></h2>
Let p be the proportion of voters in a certain state support an increase in the minimum wage.
As per given , we have
Since alternative hypothesis is right-tailed so the test is a right-tailed test.
Test statistic :
, where n= sample size.
p= population proportion.
= sample proportion.
. In a random sample of 300 fast food workers for 240 supporters increase an minimum-wage.
i.e. n= 300 and
Then,
For significant level α = .05 , the critical z-value is
Decision : Since calculated z-value (3.78) is greater than the critical value (1.645) , so we reject the null hypothesis.
Conclusion : We have sufficient evidence o support researcher's claim that that the percentage of fast food workers for support and increase is higher than 70%..
