comparison of the masses (in $\mathrm{kg}$ ) of convertible cars was made using the Large Data Set.
Do not write outside the
box
A sample of 20 masses was chosen from both the 2002 data and the 2016 data.
The masses of the 20 cars in each sample were used to create a box plot for each year.
The box plots were labelled Box Plot A and Box Plot B as shown in the diagram below.
(a) Estimate the median of the masses from Box Plot A
[1 mark]
Answer
\(\boxed{\text{The estimated median of the masses from Box Plot A is 1500 kg}}\)
Step 1 ：Estimate the median of the masses from Box Plot A by finding the value that corresponds to the middle line of the box in Box Plot A.
Step 2 ：\(\text{estimated_median_A} = 1500\)
Step 3 ：\(\boxed{\text{The estimated median of the masses from Box Plot A is 1500 kg}}\)
