0 Icon Key
gnment
The p-value is less than 0.01
What is your conclusion?
Conclude the mean time needed to mix a batch of material is not the same for all manufacturers
b. At the a= 0.05 level of significance, use Fisher's LSD procedure to test for the equality of the means for manufacturers 1 and 3.
Calculate Fisher's LSD Value (to 2 decimals).
