Hey everyone! Could someone please help me solve the following problem? Thank you so much!!

As part of a survey conducted by an "independent market basket price-checking company," the average weekly total, based on the prices (in $) of approximately 95 items, is given for two different supermarket chains recorded during 4 consecutive weeks in a particular month.

1 254.31 256.04

2 240.56 255.63

3 231.94 255.12

4 234.19 261.21
