MA In 151 Lab 5 1/2021 The goal of this lab is to standardize data, to compute probabilities using the standard normal distribution, and to find values given probabilities. For this lab you will use variable V2. (2 points) 1. Return to Lab 3 to find the values for your V2 variable. Name of your V2 variable: _ Obesily Kate What was the sample mean? 17 the standard deviation? .14 Data Value Corresponding z-score (z) Area to the left from (x) Table B Minimum Value (.0-. 17) (Min) O Z= . 14 = -1.21 1131 Median Value (Med) Choose median, not mean 17 (17-17) 06 12 : 7 14 0 .5 Maximum Value (Max) 64 ( 144-. 17 ) 14 = 0 : 3.36 , 99 96 For the rest of the lab, you will make the assumption that your data is approximately normally distributed. For some students this is a reasonable assumption; for others, it is not. You can check your histogram from Lab 2 to see whether it looks normal.
