A set of data (call it DATA A) is N(100, 10).
1) Give the z-score if a data point is at 131.
2) Give the data point value if the z-score is -2.15
3) Give the data point value if 22% of the data is lower than our data point.
4) Give the data point value if 13% of the data is higher than our data point.
5) Between what values is the middle 50% of our data?
6) What percent of the data is between 70 and 107?
A second set of data (DATA B) is N(95, 15).
1) What score is better: 115 in DATA A or 120 in DATA B?
2) A data point has value 119 in DATA A. What value is equivalent in DATA B?
