Pooled Combined Variance 
Test Statistic:
Degrees of freedom = 
The table value is greater than the calculated value.
Thus we accept H0.
How to understand the problem is like this:
Total Cost = Entrance Fee + Total Car cost
So we know that the Entrance Fee is $150...
Total Cost = $150 + Total Car cost
So we know that Anne bought 13 cars, each at $2,000...
Total Cost = $150 + ($2,000 x 13)
We multiply because each car is $2,000 and Anne bought 13 of them.
So it works out like this:
Total Cost = $150 + ($2,000 x 13)
Total Cost = $150 + (26000)
Total Cost = $26150
