7. Consider the computer output below. One-way ANO VA: y versus Factor (a) How many levels of the factor were used in this experiment? (b) How many replicates were used? (c) Fill in the missing information.. (d) What conclusions would you draw if alpha = 0.05?

Solution

(a) 4 factors were used.

(b) 15 replicates were used.

(c)

R-square=0.3678

(d) The P value equals 0.0313

The p-value is less than 0.05 significance level. therefore we reject the null hypothesis
