A manufacturer is testing its new grain moisture meter and sampled out 5 grain types (1, 2, 3, 4, 5) and measured their moisture contents at 3 trials each as shown in second table. A. Compute for the estimate of the variance between treatments, compute for the degrees of freedom between treatments. B. Compute for the estimate of the variance within treatments, compute for the degrees of freedom within treatments. C. When you are asked to compute if there is a significant difference in the means at 1% level of significance, what will be the critical f value? Indicate input arguments used in looking at the table. Compute for the observed variance ratio. What will this say about the effect of grain sample to the moisture content? D. Now supposed you were asked to determine which means are different from the rest, you conduct Fisher’s least significant difference test at 10% alpha level. Find critical t value from the t-distribution table, indicate input arguments used. What is the LSD? Check if means of sample 1 is significantly different from sample 5.

Question
A manufacturer is testing its new grain moisture meter and sampled out 5 grain types (1, 2, 3,
4, 5) and measured their moisture contents at 3 trials each as shown in second table.
A. Compute for the estimate of the variance between treatments, compute for the degrees of
freedom between treatments.
B. Compute for the estimate of the variance within treatments, compute for the degrees of freedom
within treatments.
C. When you are asked to compute if there is a significant difference in the means at 1% level of
significance, what will be the critical f value? Indicate input arguments used in looking at the table.
Compute for the observed variance ratio. What will this say about the effect of grain sample to the
moisture content?
D. Now supposed you were asked to determine which means are different from the rest, you conduct
Fisher’s least significant difference test at 10% alpha level. Find critical t value from the t-distribution
table, indicate input arguments used. What is the LSD? Check if means of sample 1 is significantly
different from sample 5.
