In a normal distribution with mean of 900 and standard deviation is 350 find the probability that a data value picked at random is greater than 1100

show work

Answer 1

1100 - 900 = 200, you are 200 units away from the mean

200/350 = .571 standard deviations away.

The mean is 50% in a Normal GAUSSIAN distribution.

Therefore, you take the 50% add the probability it will happen within .571 standard deviations, then subtract that from 100%.

That is the probability it will happen over 1100.
