The marketing manager of a home deco company in Australia wants to determine whether outlet location has any effect on their sales. Three different outlets are considered: Location A, B and C. A and their sales during last 5 months were recorded. Assume the size of the outlet and price of the product are constant for all stores.

Sales (000)
Location A	Location B	Location C
250	150	230
270	300	200
180	300	250
265	170	300
100	120	370

At the 5% level of significance, is there evidence of a significant difference in mean sales between the various aisle location? Perform the following steps:

1. State the hypothesis

2. Calculate the sample mean and variance

3. Calculate the grand mean

4. Calculate the sum of square due to treatment (SSTR)

5. Calculate the sum of square error (SSE) and mean sum of square error (MSE)

6.Calculate the F value

F= MSTR/MSE
