1. 4p + 6
2. p+ p + p + p + 6
3. 6 + 4(p)

(i) The mean is
The variance is
Compute the second moment 
:
Then the variance is
(ii) For a random variable 
, where 
are constants, we have
and
Then for 
, we have
For Beth, we know that she works 5 days a week and that she earns $54 dollars per day. Next, add the $10 dollars for each extra hour of work. p stands for the amount she gets paid.
