Given: normal distribution curve with mean = 182. standard deviation = 18. i. Select the shaded graph that best represents P( X < 164 ) [ans1] Round the answers below to 2 decimal places if necessary. For example if your answer is 0.456, you should write it as 0.46. ii. P( X < 220 ) = [ans2] iii. P( X > 170 ) = [ans3] iv. P( 150 < X < 160 ) = [ans4] v. Given that the z-score =

i. Which statement below is FALSE regarding the possible value of X as it relates to a probability distribution table: Type in the correct letter from the choices below: [ans1] a. It can be negative. b. It can be a decimal. c. All X values must add up to 100. d. You can have repeat values occur. ii. Which statement below is FALSE regarding the possible value of P(X) as it relates to a probability distribution table: Type in the correct letter from the choices below: [ans2] a. It can be negative. b. It can be a decimal. c. All P(X) values must add up to 1. d. You can have repeat values occur. For the probability distribution table shown below, calculate the expected value and standard deviation. iii. expected value = [ans3] iv. standard deviation = [ans4]
