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.
O Ho: At least two of the population means are equal.
Ha: At least two of the population means are different.

O Reject Ho. There is not sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
Reject Ho. There is sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
Do not reject Ho. There is not sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
Do not reject Ho. There is sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
