1.) Please complete the following in your textbook AND ALWAYS CHECK YOUR ANSWERS!
- Task #1 --> Page 123: 5, 9, 13
2.) What % of data falls between the mean and 1 standard deviation above the mean? Or between 1 and 2 standard deviations above the mean? Or between the mean and 1 st. dev. below the mean? Let's figure it out...
- Task #2 --> figure out what % of data falls in each interval labeled with the question marks below! Use the 68/95/99.7 rule to figure this all out....good luck!
Today we recapped/discussed z-scores and answered questions about the shifting/rescaling homework problems. Then we introduced the NOrmal model and defined the 68/95/99.7 (or Empirical) rule. Tonight we'll use this rule for task 2 of our homework.
Tomorrow we'll do some more work with the empirical rule (interpret and apply it), and then we'll start working through some more normal percentile problems--see you there!
