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. $\begin{array}{c}{H}_0:{?}_{50^{?}\mathrm{C}}={?}_{60^{?}\mathrm{C}}={?}_{70^{?}\mathrm{C}}\\ H_{\mathrm{a}}:{?}_{50^{?}\mathrm{C}}?={?}_{60^{?}\mathrm{C}}?={?}_{70^{?}\mathrm{C}}\\ H_0:{?}_{50^{?}\mathrm{C}}?={?}_{60^{?}\mathrm{C}}?={?}_{70^{?}\mathrm{C}}\\ H_{\mathrm{a}}:{?}_{50^{?}\mathrm{C}}={?}_{60^{?}\mathrm{C}}={?}_{70^{?}\mathrm{C}}\\ H_0:{?}_{50^{?}\mathrm{C}}={?}_{60^{?}\mathrm{C}}={?}_{70^{?}\mathrm{C}}\\ H\text{. Not all the population mea }\end{array}$ $H_{\mathrm{a}}:$ Not all the population means are equal. $H_0$ : At least two of the population means are equal. $H_a$ : At least two of the population means are different. $H_0:$ Not all the population means are equal. $H_a:{?}_{50^{?}\mathrm{C}}={?}_{60^{?}\mathrm{C}}={?}_{70^{?}\mathrm{C}}$ Find the value of the test statistic. (Round your answer to two decimal places.) Find the $p$-value. (Round your answer to four decimal places.) $p$-value $=$ State your conclusion. Do not reject $H_0$. There is not sufficient evidence to conclude that the mean yields for the three temperatures are not equal. Reject $H_0$. There is not sufficient evidence to conclude that the mean yields for the three temperatures are not equal. Do not reject $H_0$. There is sufficient evidence to conclude that the mean yields for the three temperatures are not equal. Reject $H_0$. There is sufficient evidence to conclude that the mean yields for the three temperatures are not equal.
