<u><em>Explanation:</em></u>
<u>The data collected by Lucilla is as follows:</u>
7.1 oz
6.9 oz
7.3 oz
7.6 oz
8.1 oz
7.5 oz
<u>We need to put this data in order, this will give us:</u>
6.9 , 7.1 , 7.3 , 7.5 , 7.6 and 8.1
<u>We can note that:</u>
smallest value is 6.9 oz
largest value is 8.1 oz
all other values fall in this range
<u>Therefore,</u> the weight of an orange based on her calculations is between 6.9 oz and 8.1 oz
Hope this helps :)
