The average male basketball player is two hundred centimeters tall. I know that he is taller than the average male baseball player and both are taller than the average man. I wonder what percent of men are 200 cm 187 cm 175.5 cm 1. Show Jenna (actor: Patricia) in the dining room. 2. Show a male basketball player (tall). Add label beneath: “200 cm”. 3. Show a male baseball player (middle height). Add label beneath: “187 cm”. 4. Show an average man (shortest height). Add label beneath: “175.5 cm”. 5. Show Jenna close up. shorter than the average basketball player. NG_AL2 _T_03_D ay1_GR_ MathIntr o_02.mp 3 What percentage of men is shorter than two hundred centimeters? Over fifty-five percent, over seventy-five percent, or over ninety-five percent? What percentage of men is shorter than two hundred centimeters? 1. Change to Male Adult VO Background Image ID_245637325 Use this backdrop as the screen for the following steps. Over 55% Over 75% Over 95% Over ninety-five percent! Let’s find out why. NG_AL2 _T_03_D ay1_GR_ Heights of men are normally distributed with a mean of one hundred seventy-five point five Heights of men are normally distributed. 2. Highlight ‘over 95% 1.Show OST sentence 2. Show “Mean = 175.5 cm” 3. Show “Standard Deviation = 7.37 cm” MathIntr o_03.mp 3 NG_AL2 _T_03_D ay1_GR_ MathIntr o_04.mp 3 centimeters and a standard deviation of seven point three seven centimeters. Mean = 175.5 cm This means that the distribution of heights can be shown as a bell curve, with one hundred seventyfive point five centimeters in the middle. [FRO 4] To determine the percent of heights that are below two hundred centimeters, we want the area under the bell curve below x equals two hundred. [FRO1] Using a graphing calculator, we see that this area is zero point nine seven five, which means ninetyseven point five percent of men are shorter than two hundred centimeters tall. Standard Deviation = 7.37 cm 4.Show the image as shown below, title of graph “Male Height,” label the horizontal axis “Height (cm)” 1.Keep the graph from last scene. Show the OST “x = 200” with vertical line and shade under the bell curve to the left of the line. Area = 0.975 97.5% of adult males are shorter than 200 cm 2. Show OST “Area = 0.975”. 3. Show final OST. NG_AL2 _T_03_D ay1_GR_ MathIntr o_05.mp 3 By examining the normal distribution, I know that almost ninety-eight percent of men are actually shorter than the average basketball player. 1. Show Jenna back on screen.
