From 1984 to 1985, the mean height of 15 to 18-year-old males from Chile was 172.36 cm, and the standard deviation was 6.34 cm. Let Y= the height of 15 to 18-year-old males from 1984 to 1985. Then Y~ N(172.36, 6.34). 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). Find the z-scores for x = 160.58 cm and y = 162.85 cm. Interpret each z-score. What can you say about x = 160.58 cm and y = 162.85 cm as they compare to their respective means and standard deviations?

Question
Transcribed Image Text:From 1984 to 1985, the mean height of 15 to 18-year-old males from Chile was 172.36 cm, and the standard
deviation was 6.34 cm. Let Y= the height of 15 to 18-year-old males from 1984 to 1985. Then Y~ N(172.36,
6.34).
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).
Find the z-scores for x = 160.58 cm and y = 162.85 cm. Interpret each z-score. What can you say about x = 160.58
cm and y = 162.85 cm as they compare to their respective means and standard deviations?
