Name Statistics Date 7.1 Worksheet B In problems 1-4, given the mean and standard deviation, use the 68-95-993 Rule to solve for each value of the data set. Write your answer as an inequality. 1. Mean u = 10, o = 3, what x-values 1ie within 68% of the data set? 2. Mean p. = 32, a = 8, what x-values lie within 99.7% of the data set? 3. Mean u = 24.8, o = 4.8, what x-values lie in the highest 2.5% of the data set? 4. Mean u = 30, o = 12.5, what x-values lie in the lowest 16% of the data set? In problems 5-10, use a standard z-table or technology (graphing calculator) to determine the area under the normal curve. 5. z > 0 6. z s O 7. zn1.25 9. -12
