I Application: Drug Trials
Discuss the questions below in Discussion: Explaining Simpson's Paradox
A company runs two trials of two treatments for an illness. In the first trial, Treatment A cures 20% of the cases (40 out
of 200) and Treatment B cures 15% of the cases (30 out of 200). In the second trial, Treatment A cures 85% of the cases
(85 out of 100) and Treatment B cures 75% of the cases (300 out of 400).
a) Calculate the overall cure rate for Treatment A and Treatment B.
Treatment A overall:
%
Treatment B overall:
%
b) Which treatment had the better cure rate in the two trials individually?
Which treatment had the better cure rate overall?
Explain the apparent inconsistency in these results.

understand that i don't know the answers

will someone answer his question

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

1. sometimes

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
