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
50°C	60°C	70°C
34	30	23
24	32	28
36	34	29
38	22	29
28	27	36

Construct an analysis of variance table. (Round your values for MSE and F to two decimal places, and your p-value to four decimal places.)

Source of Variation	Sum of Squares	Degrees of Freedom	Mean Square	F	p-value
Treatments	?	?	?	?	?
Error	?	?	?
Total	?	?

Find the value of the test statistic. (Round your answer to two decimal places.)

SUMMARY
Groups	Count	Sum	Average	Variance
50°C	5	160	32	34
60°C	5	145	29	22
70°C	5	145	29	21.5

treatment	30	2	15	0.58	0.5745
Error	310	12	25.83
Total	340	14

the value of the test statistic is 0.58

the p-value is 0.5745
