Answer:
B. The difference of the medians is about one-fourth the interquartile range of either data set
Step-by-step explanation:
Given the heights of preschool boys in cms
105.1 104.8 101.3 87 86.7 95 93.8 92.1 92.4 100
Arrange them in ascending order
86.7 87 92.1 92.4 93.8 95 100 101.3 104.8 105.1
Median = 93.8: Q1 = 87:Q3=101.3
IQR = Q3-Q1 = 4.3
Given the heights of preschool girls in cms
85.2 90.3 99.6 98.6 97.5 101.7 102.9 89.4 107 92
Arrange them in ascending order
85.2 89.4 90.3 92 97.5 98.6 99.6 101.7 102.9 107
Median = 97.5: Q1 = 89.4:Q3=101.7
IQR = 4.2
Differnce in the medians = 3.7
Diff in IQR = 0.1
B. The difference of the medians is about one-fourth the interquartile range of either data set because
0.4 = 4(0.1)
Answer:
