Solutions

Expert Solution

3)   mean = 233 , standard deviation =16, Percentile = 90th

value of the 90th percentile = 254

4)  mean = 58.5 , standard deviation =4.35 Percentile = 1st

the height at the 1st percentile = 48.3803

5) mean = 96 , standard deviation =5 , Percentile = 25th

value of the 25th percentile =92.6

6)mean = 98.38 , standard deviation =0.5. Percentile = 25th

the value of the first quartile = 98.0428

7) mean = 98.46 , standard deviation =0.32, Percentile = 75th

the value of the third quartile = 98.68

8)mean = 90 , standard deviation =7, Percentile = 25th

he value of the first quartile = 85.3
