Question

Marcus is examining a histogram based on a dataset. He notices that the data is roughly symmetrical around a single peak at 50. The mean of the data is at 50.5 and the +1σ point is at 60.5. What is the normal model for the data distribution?
A. (50,60.5)
B. (50,10.5)
C. (50.5,10)
D. (50.5,60.5)

Answer 1

is this right

Answer 2

which is right

Answer 3

Is it (50,60.5) or (50.5,10)

Answer 4

D. (50.5,60.5)

Answer 5

Apologies for the confusion in my response. The correct answer is A. (50,60.5). The normal distribution model for the data distribution is with a mean of 50 and a standard deviation of 10.5 (since +1σ is at 60.5).

Answer 6

I apologize for the confusion in my responses earlier. The correct answer is A. (50,60.5). Thank you for catching that error.
