URGENT!!

Independent random samples of the selling prices (in 10 000 TL ) of houses in three popular districts of four big cities were taken. The selling prices are as shown below. Assume that the populations from which the sample drawn are normally distributed. (use 2 digits after decimal point)

	District A	District B	District C
Ankara	45	52	54
İstanbul	46	51	58
İzmir	40	60	50
Bursa	37	49	46

2.   At the 0.05 significance level, are the mean selling prices differ by districts?

a) Null Hypothesis is

Ho: Mean selling prices for different districts are not equal

Ho: Mean selling prices for different districts are equal

b)  Alternative Hypothesis is

H₁: Mean selling prices for different districts are equal for at least one pair

H₁: Mean selling prices for different districts are not equal for at least one pair

c)  F-Ratio is Answer

d) Critical Value of the test at a=5% is Answer

e)  Does it appear at a=5% that population means are different ?

May be

Yes for at least one pair

No
