2) Paasche Price Index (10 points):

	Price per lb. 2007	Qty. bought in 2007	Price per lb. 2008	Qty. bought in 2008
Onions	$ 2.25	9	$ 2.30	7
Garlic	$ 4.50	7	$ 5.00	8
Tomatoes	$ 1.75	20	$ 1.65	10

Calculate the inflation rate between 2007 and 2008. Use the Paasche Price Index with 2007 as the base year. You need to get the price indices first before you can calculate the inflation rate. (10 points)

	Coefficients	Standard Error	t Stat	P-value	Lower 95%	Upper 95%
Intercept	52.25	12.37		0.023	47.56114	56.91386
YEARS	1.49	0.53		0.002	0.267298	2.714904

The table above shows the regression results for the model:

Wage = + YEARS +

Where: wage is the hourly wage and years is the number of years of experience.

Given the regression results, how much should an individual with 19 years of experience earn? (5 points)
