Do you know how to solve for your error margin?
  • phi
this is the same problem as your "customer service" problem, but with different numbers
So given: That the the sample mean is 83 The error margin is 1.96^2 / Squa*64 -> Which gives = 0.49 Approximately Now the range is from 83 - 0.49 < u < 83 + 0.49

I got 82.51, 83.49
those aren't in the multiple choice
yes I know one second
I think it would be 83.2?
|dw:1433333812983:dw|
|dw:1433334016477:dw|
They are both equally far apart
nope
|dw:1433334121303:dw|
Am I looking for the farthest away? since it says outside the 95% confidence interval
i don't know how to calculate the 95% confidence interval, but yes you are looking for the option that are furthest from the mean
so 83.6
if any of the options are correct yes that must be one of them, but if there are multiple correct options i cant be sure about 82.8 and 83.4, either they are both correct also or both incorrect
Okay thank you!
if we use @DelTaVsPi 's result :
Can you help me with one more?

i don't know stat.
The answer was right...
The answer is always right!
Lol
For the second question if you can help its which of the following is an example of replication A. Assigning test subjects to test groups arbitrarily B. performing five different studies of the same drug C. testing patients by giving them either a new drug or no drug D. studying the effects of both therapy and no therapy on students
the first option seems to define randomization and the last two options seam to be examples of a controlled experiment
So it would be B since repeating the same experiment on different people
makes the most sense, if the results for the 5 studies agree; these replicated results will be much stronger evidence
I dont know why I said people xD
People are everywhere!
