1. The table below shows the amount of hours students watch tv during the school week. Part 1) Use the table to label the axis for your histogram accordingly. Part 2) Determine the probability the event would occur in the last column. Hint: # of Students/ Total Students Part 3) Create a histogram using the first TWO columns of the table. Part 4) Answer the questions below related to probability of the given situation(s). Hours of TV 0-4 5-9 10-14 15-19 20-24 # of Students 20 40 60 80 50 Probability 20/250 40/250 60/2.50 80/250 50/250 Frequency (Number of Students) 300 200 260 240 220 200 180 160 540 100 So 60 40 20 *Remember probability should add to 1* What is the probability a student watches between 10-14 hours of tv? 0.24 Hours of Television Per Week What is the probability a student watches between 5-9 or 20-24 hours of tv? What is the probability a student watches 14 or less hours of tv? What is the probability a student watches 5 or more hours of tv? 0.48 0.36
