... Make a diagram! For z draw a Normal curve with zero in the middle. Shade the area between -3.32 and 0.22 and note that it is all on one side of the mean, so that you subtract the area between -0.22 and zero from the area between -3.32 and zero. ...

Normalizing data.
... We often want to compare scores or sets of scores obtained on different scales. For example, how do we compare a score of 85 in a cooking contest with a score of 100 on an I.Q. test? In order to do so, we need to “eliminate” the unit of measurement, this operation is called to normalize the data. Th ...

... We want to estimate the year 2000 mean PH level of rain in Pierce County Washington in order to see if it is lower than the 5.03 pH level from the year 1990. If the PH has decreased, then we can conclude that the acidity of rain in that area has increased. b) Use the calculator to construct the inte ...
