Sagot :

Using the mean concept, it is found that the correct option is:

A. Chawrdi complied with the guideline because the mean number of hours played is approximately equal to 3.17.

  • The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In this problem:

  • On the six-day period, the observations, that is the number of hours he played each day are given by: 2, 1, 4, 5, 0 and 7.

The mean is:

[tex]M = \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = \frac{19}{6} = 3.17[/tex]

Mean is less than 3.5, thus she complied with the guidelines, and the correct option is:

A. Chawrdi complied with the guideline because the mean number of hours played is approximately equal to 3.17.
