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.
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 Selectless than .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 11
What is your conclusion?
SelectConclude that the mean yields for the three temperatures are not all equalConclude that the mean yields for the three temperatures are all equalItem 12
