Suppose a variable (X-height) can be modeled with a normal distribution with a mean of 70 inches and standard deviation of 4 inches. A guy in my class last semester was six foot 9 inches (81 inches tall)! What are the chances a random selected person would be taller than 81 inches? That is find P(X>81). 0.0022 0.997 O 0.5 0.003
Question 10 (1 point) Listen Suppose a variable (X-height) can be modeled with a ndrmal distribution with a mean of 70 inches and standard deviation of 4 inches. A guy in my class last semester was six foot 9 inches (81 inches tall)! His Z-score is 2.75 If Z is a standard normal variable, the probability calculation P(Z>2.75) will be the same as the computation from the previous answer
question P(X>81). True False
