Given
The above table
Required
Determine the mean
The mean is calculated as thus:
Mean = Summation of x * P(x)
So, we have:
Mean = 1 * 0.14 + 2 * 0.16 + 3 * 0.12 + 4 * 0.14 + 5 * 0.13 + 6 * 0.31
Mean = 0.14 + 0.32 + 0.36 + 0.56 + 0.65 + 1.86
Mean = 3.89
Mean = 3.9 (approximated)

1h = $18.25
a) She works 40 hours per week and for one hour she makes $18.25, so in order to find out her weekly income you need to multiply $18.25 by 40.
$18.25 × 40 = $730
Her weekly income is $730 if she works 40 hours per week.
b) She makes $730 a week and there are 52 weeks in a year, so in order to find out her yearly income you need to multiply $730 by 52.
$730 × 52 = $37 960
Her yearly income is $37 960 if she works 40 hours per week for 52 weeks.
