Exercise 12 The IBDA class of 2012 population parameters for height are p. = 170.13 cm and o = 9.96 cm. . Calculate the z-score for a person of height 181 cm . Calculate the z-score for a person of height 163 cm Exercise 14 By convening a value from a normally distributed sample or distribution into a z-score, we can determine the probability of getting that value. You will use the z-scores calculated in Exercise 12 to answer the following questions: a} A student is 181 cm tall. Sketch this on a 2-distribution. Then, determine what the area under the curve to the left of this person's height is. b} What percentage of students is taller than 163 cm? (you should sketch this on a z-distribution too, as part of your answer) c) What percentage of students is shorter than 163cm or taller than 131 cm? (you should sketch this on a 7.- distribution too, as part of your answer)
