Class Parameters vs. Personal Sample Data The results from the data collection from all last year's stat classes from Part 1 of the Project is below. Your statistics from Part 1 needs to be used as sample data for all the Steps of Part 2. The parameters below will be used in Step 2, 3 & 4 along with yours. Population Mean
\mu =19.6
(minutes) Pop. Standard Deviation
\sigma =10.5

Step 1 Exploring Your Statistics Label a normal curve for your data with mean and 3 standard deviations, the same for each question, labeling your axes ( X and Z ), as you did at the end of Part 1. Then answer the following questions, drawing pictures (shading appropriately), showing all equations for support. A. What would be your corresponding
x
- value to a
z
- score of -0.56 ? What percentage of your focused study times were at, or less than, that score?
