Slope is 2/5 and the y into is -1/3
I just went with the slope. So I am not sure about the y-int.
Slope= y2 -y1 over x2-x1
(-2/15–1/30) =-.1
—————————- (over)
(-1/2- -3/4) =. -.75
- 0.1 / - 0.25 = .4 = 2/5
Answer:
Null and alternative hypotheses:
H0: p1 = p2
H1: p1 ≠ p2
To find the sample proportions, we have the following:
Calculate Z statistics:
Z = -2.764
P-value = 0.00285
The pvalue is low.
Since the pvalue is low, reject null hypothesis, H0.
Conclusion:
There is strong evidence that patients experiencing the primary outcome is different for those receiving the treatment compared to those without
