a. At the a = 0.05 level of significance, can we reject the null hypothesis that the means of the three treatments are equal?
Compute the values below (to 1 decimal, if necessary).
Sum of Squares, Treatment
Sum of Squares, Error
Mean Squares, Treatment
Mean Squares, Error
Calculate the value of the test statistic (to 2 decimals).
The p-value is less than 0.01
What is your conclusion?
Conclude that not all treatment means are equal
b. Calculate the value of Fisher's LSD (to 2 decimals).
