Answer:
Step-by-step explanation:
Given that Advandia is a drug used to treat diabetes, but it may cause an increase in heart attacks among a population already susceptible.
Sample size n =1`456
Sample proportion of persons having heart attack p1= 27/1456 = 0.0186
II sample
Size = 2895
p2 = sample proportion = 41/2895 = 0.0142
a) Not matched pair data but independent proportions
b)
Step 1:
(right tailed test at 5% significance level)
Step 2: Test statistic z = 1.0995
Step 3: p value = 0.13567
Step 4: Since p >0.05 accept null hypothesis.
There is no evidence to suggest that there is a significant increase in the proportion of people who suffer heart attacks when using Avandia compared to other treatments.

Answer:
The positive graph is on the points (-5,-4) and (2,5)
And, negative would be (-4,2)
Step-by-step explanation:
As it seems that fgraph shows positive in the case when it is over x-axis, and negative when it is below y-axis
As on the interval (-1,5)
The graph is below x-axis i.e. on (-1,2)
And, over x-axis i.e. on (2,5)
At this point Lonzell’s is not correct
As on the interval (-5,-1)
The graph is below x-axis i.e. on (-4,-1)
And, over x-axis i.e. on (-5,4)
At this point Lonzell’s is not correct
So,
The positive graph is on the points (-5,-4) and (2,5)
And, negative would be (-4,2)
