To test whether the mean time needed to mix a batch of material is the same...

Manufacturer 1	Manufacturer 2	Manufacturer 3
25	34	18
31	32	17
29	37	21
27	33	20

a. use these data to test whether the population mean times for mixing a batch of different material differs for the three manufacturers. use .05

Compute the Values below

Sum of squares, treatment
sum of squares, error
mean squares, treatment
mean squares, error

Calculate the value statistic

B. a the .05 level of significance, use the fisher LSD procedure to test the equality of the means for manufacturer 1 and 3

Calculate Fisher's LSD value
