Answer:
Based on statistical analysis the claim is of 3% of patients developing adverse reaction is valid and there is a drug problem
Step-by-step explanation:
Here we have
Percentage of patients that develop nausea em= 153/5783 *100 = 2.65 %
To test the hypothesis, we put our null hypothesis as
H₀: μ = 3%
Alternative hypothesis is then
Hₐ: μ < 3%
Therefore the test statistic is
P₀ = 0.03
= 0.0265
n = 5783
From the above we have our test statistic as -1.579 from which gives our p value as P = 0.057.
Therefore, as we have our P value less than the confidence level of 0.05, we therefore fail to reject the null hypothesis because there is sufficient statistical evidence that suggest that the proportion of patients who would have adverse reaction to the drug = 3%.

Answer: 4</h3>
======================================================
Explanation:
We can pick any (x,y) point on this blue line as long as we don't pick (0,0)
This is because we cannot divide by zero.
Let's say we pick the point (x,y) = (1,4)
The constant of proportionality is found like so
k = y/x
k = 4/1
k = 4
The constant of proportionality is 4
Or we could pick a point like (2,8) to get
k = y/x
k = 8/2
k = 4
We get the same thing.
There are infinitely many points to pick, but in my opinion, it's easiest to stick with (1,4).
As a slight alternative, you can apply the slope formula (pick any two points you want on the blue line) and you should get 4 as well.
-----------------
Extra info:
- The direct proportion equation always goes through the origin. This means the y intercept is 0.
- The slope is equal to the constant of proportionality.
- The equation of this line is y = 4x
