Answer 2

Answer:

a.) Check attatched image for boxplot drawing.

b.) 45 boys.

Step-by-step explanation:

b.) A box plot is split up into 4 quarters:

Minimum to Lower Quartile

Lower Quartile to Median

Median to Upper Quartile

Upper Quartile to Maximum

So looking at  the question it asks for you to find the number of boys between 149cm (Lower Quartile) and 181cm (Maximum) which all together is 3/4 of the boxplot. Knowing this, take the total number of boys (which is 60) and multiply it by 3/4 which will give you the final answer of: 45 boys.
