Question

The double dot plot represents the number of tourists visiting two beaches in 15 days.

Choose the correct option.

• A. IQR of beach B = 42
• B. IQR of beach A = 44
• C. Median of No.of tourists visiting Beach B = 38
• D. Median of No.of tourists visiting Beach A = 42

Answer 1

The correct option is D Median of No.of tourists visiting Beach A = 42

For Beach A:
Median = 42
Median of lower half (Q1) = 38
Median of upper half(Q3) = 46
IQR = Q3-Q1
= 46-38
= 8

For Beach B:
Median = 40
Median of lower half (Q1) = 36
Median of upper half(Q3) = 44
IQR = Q3-Q1
= 44-36 = 8
Here,
IQR(beach A) = IQR(beach B)
