Answer #1
solution:-
given values
148,145,135,138,120,125,133,130,125,149,120,140,147,150
arrange in order
120 ,120,125 , 125,130,133,135,138 ,140 , 145 ,147,148 ,149,150
=> Boxplot
5 number summary
=> minimum = 120
=> quartile Q1 = 125
explanation :- The first quartile is the median of the bottom half
of the numbers
=> median = 136.5
explanation:-median = (135 + 138)/2 = 136.5
=> quartile Q3 = 147
explanation:- The third quartile is the median of the upper half of
the numbers
=> maximum = 150

1. Construct a frequency distribution with density using the
intervals corresponding to the American Heart Association’s blood
pressure categories for systolic blood pressure: normal: [100,120),
elevated: [120,130), hypertension stage 1: [130,140), hypertension
stage 2: [140,180), and hypertensive crisis:...
