To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material.
| 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
