If the mean weight of some data is 22 and the standard deviation is 2. what percent of the data will weigh more than 20 pounds?
84.1%. http://en.wikipedia.org/wiki/Standard_deviation
Added:
50% of the weights will be above the mean. 34.1% will be below the mean by one standard deviation or less.
Help me out here. It's been a long time.
The area encompassed by one SD on either side of the midline of the Gaussian curve is about 64% of the total. So half of that 32% + 50% gives you your answer.
Is that how you did this?
