SOLUTION 9: The percentage of measurements that people are above the 39th percentile is...61%
SOLUTION 10 : {10, 12, 12, 15, 15, 15, 18, 20, 22, 25, 25, 26, 29, 30, 32, 33, 40, 40, 40, 45, 46, 47, 48, 48, 50, 52, 53, 56}
Minimum: 10
Quartile Q1: 19
Median: 31
Quartile Q3: 46.5
Maximum: 56
Interquartile range= Q3-Q1= 46.5-19= 27.5
11) Minimum: 2.9
Quartile Q1: 5.7
Median: 10.0
Quartile Q3: 13.2
Maximum: 21.1
Interquartile range= Q3-Q1= 13.2-5.7= 7.5
12) LF= Q1-1.5*IQR= 5.7-1.5*7.5= 5.7-11.25= -5.55
UF= Q3+1.5*IQR= 13.2+1.5*7.5=13.2+11.25=24.45
note: I have done the first four questions. Please repost rest questions along with the data.
