Provide a range for the p value using the tables provided on the course website. round all non-integer values to nearest 0.001 F Source df SS MS Among Within Total (d, 3 pts) What is your conclusion? Use the grammar described in lecture and state with what degree of confidence you make your conclusion by providing the most specific range of p values from the table provided in lecture. You must use the phrase "significantly different" or not significantly different" in your answer. Also, if any means appear to be different make your best guess as to the most likely pair that differ. Note: no credit will be given for ANY text outside the box or hard to read answers.
