Question

a shop only buys bananas with length between 13cm and 20cm. Estimate the fraction of the 80 bananas that the shop buys

Answer 1

44/80

Explanation:

Answer 2

`(44)/(80)`

Explanation:

We know that the shop only buys Banana with lengths between 13 cm and 20 cm.

So, the fraction of the 80 bananas is actually a ratio between the y-values of each length (13 and 20 cm) and the total 80. First, let's see which y-values belong to each length.

Notice that 13 below to 20 at Cumulative Frequency. And 20 belongs to 62. So, the pairs are (13,20) and (20,62).

`(62-20)/(80) =(42)/(80)`

Therefore the shop only buys 42 bananas out of 80, because those are between 13 cm and 20 cm.
