To study the effect of temperature on yield in a chemical process, five batches were produced at each of the three temperature levels. The results follow.

Temperature
50C	60C	70C
35	29	23
25	32	29
35	33	27
38	23	31
27	23	25

Construct an analysis of the variance table. (Round your values for MSE andFto two decimal places and yourp-valueto four decimal places.)

Use a 0.05 level of significance to test whether the temperature level has an effect on the mean yield of the process.

State the null and alternative hypotheses. (Select right answer 1,2,3 4, or 5)

1. H₀: Not all the population means are equal. H_a:_50C=_60C=_70C
2. H₀: At least two of the population means are equal. H_a: At least two of the population means are different.
3. H₀:_50C=_60C=_70C H_a:_50C60C70C
4. H₀:_50C60C70C H_a:_50C=_60C=_70C
5. H₀:_50C=_60C=_70C H_a: Not all the population means are equal.

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

Find thep-value. (Round your answer to four decimal places.)

State your conclusion.

• Do not rejectH₀. There is not sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
• RejectH₀. There is not sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
• Do not rejectH₀. There is sufficient evidence to conclude that the mean yields for the three temperatures are not equal
• .RejectH₀. There is sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
