Question 4) Solution:
We have given data is ,
49,52,52,52,74,67,55,55
Given data in increasing order is 49 ,52 , 52, 52, 55, 55, 67, 74
We know that second quartile = Median
We can see data has 8 observations.
Second quartile = Median = [(n/2)+(n+1)/2]/2 th observation
= [4th observation + 5th observation]/2
= [52+55]/2
= 53.5
Option c) is correct.
Question 10) Solution:
Probability of selecting someone who was sentenced to prison or entered a plea of guilty
= P[selecting someone who was sentenced to prison or entered a plea of guilty]
=P[selecting someone who was sentenced to prison ]+P[entered a plea of guilty]-P[selecting someone who was sentenced to prison and entered a plea of guilty]
=278/881+649/881-193/881
=734/881
=0.8331
