Step-by-step explanation:
Estimation, 11. ... State the mean and variance of the sampling distribution of the mean ... distribution of the mean is the population variance divided by N, the sample ... (optional) This expression can be derived very easily from the variance sum ... The standard error is represented by a σ because it is a standard deviation.
For the same amount set up two equations set equal to each other.
$70h + 130 = 80h + $40
Subtract 80h from both sides
-10h + 130 = 40
subtract 130 from both sides
-10h = -90 divide both sides by -10
h = 9 hours
CHECK
70(9) + 130 = $760
80(9) + 40 = $760
