In a small survey 350 car owners from four districts P, Q, R, S were found to have cars in price ranges A, B, C, D, the frequencies of the prices being as shown in the table.

		P	Q	R	S
Price of Car	A	9	10	12	19
	B	13	20	18	29
	C	24	29	12	25
	D	34	41	18	37

Find the expected frequencies on the hypothesis that there is no association between the district and the price of the car. Use 0.05 level of significance to test the hypothesis.
