• 1. type answer here. z-score
• 2. type answer here. kth percentile
• 3. type answer here. quartiles
• 4. type answer here. interquartile range
• 5. type answer here. z score for the 34 week gestation period baby: -0.303 z score for the 40 week gestation period baby: -0.426 The 40 week old baby weighs less relative to the gestation period.
• 6. type answer here. 34 week gestation period baby has a z score of 0.606 40 week gestation period baby has a z score of 0.851 The 40 week baby weighs less relative to the gestation period
• 7. type answer here. The men are relatively taller with a standard deviation of 1.8 and the women with a standard deviation of 1.55.
• 8. type answer here. The women are relatively taller because they are closer to the standard deviation than the males. The male is shorter than the average man more than the female is to the average women.

1. type answer here. 5% of 36 month old males weigh 12.0kg or less. 95% of 36 month old males weigh more than 12.0kg
   
2. type answer here. 95% of newborn females is 53.8cm or less. 5% of newborn females weigh more than 53.8cm.

1. type answer here. Q1 or the 25 percentile is less than or equal to 252.4 crime rates. Q2 is less than or equal to 33.8 crime rates. Q3 is less than or equal to 454.5 crime rates.
2. type answer here. The IQR is the difference between the third and first quartiles. 454.5-252.4=202.1 is the interquartile range.
3. type answer here. This value is an outlier because it is extreme. If you calculate the upper fence it is 454.5+1.5(202.1)= 757.65. Anything over this upper fence value is considered an outlier which 1243.7 is.
4. type answer here. I believe the distribution of violent crime rates is skewed because the lower fence is -50.96 and the upper fence is 757.65. There are extreme values causing this distribution to be skewed. ###3.5
