State the null and alternative hypotheses. Ho: Not all the population means are equal. Ha: H1 = M2 = H3 = H4 O HO: H1 = H2 = M3 = H4 Ha: Not all the population means are equal. HO: H1 * #2 * H3 * H4 Ha: H1 = M2 = M3 = 14 Ho: At least two of the population means are equal. Ha: At least two of the population means are different. HO: H1 = H2 = M3 = H4 Ha: H1 * H2 # M3 # H4 Find the value of the test statistic. (Round your answer to two decimal places.) 3.02 X Find the p-value. (Round your answer to four decimal places.) p-value = 0.0607 X What is your conclusion? Do not reject Ho. There is not sufficient evidence to conclude that the mean drying times for the four robots are not all equal. Reject Ho. There is sufficient evidence to conclude that the mean drying times for the four robots are not all equal. Do not reject Ho. There is sufficient evidence to conclude that the mean drying times for the four robots are not all equal. Reject Ho. There is not sufficient evidence to conclude that the mean drying times for the four robots are not all equal
