STAT E-50 - Introduction to Statistics Gathering Data; Probability 1. Ten percent of us are left-handed. In a study of dexterity, people are randomly selected in groups of five. Use a random number table to develop a simulation for finding the probability of getting at least one left-handed person in a group of five. What is the component to be repeated? Page 1

Use a random number table to develop a simulation for finding the probability of getting at least one left-handed person in a group of five. What is the component to be repeated? Selecting a person How will you model the outcome? Page 2
STAT E-50 - Introduction to Statistics Gathering Data; Probability 1. Ten percent of us are left-handed. In a study of dexterity, people are randomly selected in groups of five. Use a random number table to develop a simulation for finding the probability of getting at least one left-handed person in a group of five. How will you model the outcome? Since 10% are left-handed, let the digit 0 represent a left-handed person, and let digits 1 - 9 represent right-handed people. How will you simulate the trial? Page 3

STAT E-50 - Introduction to Statistics Gathering Data; Probability 1. Ten percent of us are left-handed. In a study of dexterity, people are randomly selected in groups of five. Use a random number table to develop a simulation for finding the probability of getting at least one left-handed person in a group of five. How will you simulate the trial? Choose groups of five numbers and count how many left-handed people are represented. What is the response variable? Page 4

Use a random number table to develop a simulation for finding the probability of getting at least one left-handed person in a group of five. What is the response variable? In what percent of the trials did we select at least one left-handed person out of the five people selected? Page 5
