Question
To study the effect of temperature on yield in a chemical process, five batches were produced at each of three temperature levels. The results follow.
Temperature
Construct an analysis of variance table (to 2 decimals, if necessary). Round p-value to four decimal places.
*Fill in blanks
Use a .05 level of significance to test whether the temperature level has an effect on the mean yield of the process.
The p-value is (pick one): less than .01, between .01 and .025, between .025 and .05, between .05 and .10, greater than .10
What is your conclusion? -> mean yields are all equal/notequal?
