This lab has three goals: 1) to standardize data by converting it to z-scores using the mean and standard deviation, 2) to compute probabilities using the standard normal distribution table, and 3) to find data values given probabilities. The student will use a variable called Heightininches from Lab 3 with a sample mean of 48.38 and standard deviation of 3.5. The student will locate z-scores for the minimum and maximum values of this data on the standard normal distribution graph and shade the corresponding areas to find the probabilities.

1. MATH 131 Lab 5 The goal of this lab is to standardite dote, to compute probabilities using the
standard normal distribution, and to find volues given probabilities. For this lab you will use
warloble ve. Part 1. 1. Return to lob3 to find the values for your V2 variable. Name of your V2
variable: Heightinivehes What was the sample mean? 48.38 the standard deviation? 3.5 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. - Locate z-scores for minimum
and maximum values in the graph. - Shade the appropriate area. - Use the values in the last
column of the table above to find the area and probability. 2. Find P (minimum value
