QUESTION 8 In a normal distribution, x = -5 and its z = -3.14. This tells you that x = -5 is standard deviations to the (right or left) of the mean. QUESTION 9 What is the z-score of x, when x = 10 and X ~ N(20,3)? (round to nearest hundredth) If your answer is a whole number, just type that number- no decimal place QUESTION 10 Fill in the blanks. Jerome averages 16 points a game with a standard deviation of four points. X ~ N(16,4). Suppose Jerome scores ten points in a game. The z-score when x = 10 is -1.5. This score tells you that x = 10 is standard deviations to the (right or left) of the mean (What is the mean?). QUESTION 11 The mean height of 15 to 18-year-old males from Chile from 2009 to 2010 was 170 cm with a standard deviation of 6.28 cm. Male heights are known to follow a normal distribution. Let X = the height of a 15 to 18-year-old male from Chile in 2009 to 2010. Then X ~ N(170, 6.28) Suppose a 15 to 18-year-old male from Chile was 176 cm tall from 2009 to 2010. The z-score when x = 176 cm is z = (round to nearest hundredth). This z-score tells you that x = 176 cm is standard deviations to the (right or left) of the mean of QUESTION 12 The mean height of 15 to 18-year-old males from Chile from 2009 to 2010 was 170 cm with a standard deviation of 6.28 cm. Male heights are known to follow a normal distribution. Let X = the height of a 15 to 18-year-old male from Chile in 2009 to 2010. Then X ~ N(170, 6.28). Suppose that the height of a 15 to 18-year-old male from Chile from 2009 to 2010 has a z-score of z = -2. What is the male's height? (to the nearest hundredths). The z-score (z = -2) tells you that the male's height is standard deviations to the (right or left) of the mean
