Answer:
Learning task 1:
1. Q1= 61
Q1 ( lower quartile) = 0.25 (n+1)
First arrange the data in increasing order : 52,57,58,61,63,66,66,68,69,70,73,75,77,83,88
Q1= 0.25(n+1)
= 0.25(15+1)
= 0.25(16)
= 4
meaning, the lower quartile is the 4th data which is 61.
2. Q3= 75
Q3 ( upper quartile) = 0.75(n+1)
Q3 = 0.75(n+1)
= 0.75(15+1)
= 0.75(16+1)
= 12
meaning, the upper quartile is the 12th data which is 75.
Q3 = 75
