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
	50C	60C	70C
	36	30	29
	26	31	34
	38	34	34
	41	23	36
	34	27	37

Construct an analysis of variance table (to decimals but p-value to decimals, if necessary).

Use a level of significance to test whether the temperature level has an effect on the mean yield of the process.

Calculate the value of the test statistic (to decimals).

The -value is - Select your answer -less than 0.01between 0.01 and 0.025between 0.025 and 0.05between 0.05 and 0.10greater than 0.10Item 12

What is your conclusion? - Select your answer -Conclude that the mean yields for the three temperatures are not all equalDo not reject the assumption that the mean yields for the three temperatures are equalItem 13
