Using it's concept, it is found that the sample mean of cars sold per week is of 4.96.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the sum of the 26 observations is given by:
S = 1 + 1 + 4 + 2 + 4 + 10 + 8 + 5 + 9 + 6 + 1 + 5 + 6 + 5 + 7 + 1 + 4 + 6 + 8 + 9 + 2 + 5 + 9 + 5 + 3 + 3 = 129.
Hence the mean is given by:
M = 129/26 = 4.96.
