You may need to use the appropriate technology to answer this question. How long it takes paint to dry can have an impact on the production capacity of a business. An auto body & paint business invested in a paint-drying robot to speed up its process. An interesting question is, "Do all paint-drying robots have the same drying time?" To test this, suppose we sample five drying times for each of different brands of paint-drying robots. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. Suppose the following data were obtained. Robot 1 Robot 2 Robot 3 Robot 4 129 143 134 149 137 133 142 143 134 141 138 136 123 146 136 139 142 132 130 153 At the 𝛼 = 0.05 level of significance, test to see whether the mean drying time is the same for each type of robot. State the null and alternative hypotheses. H0: At least two of the population means are equal. Ha: At least two of the population means are different. H0: 𝜇1 ≠ 𝜇2 ≠ 𝜇3 ≠ 𝜇4 Ha: 𝜇1 = 𝜇2 = 𝜇3 = 𝜇4
H0: 𝜇1 = 𝜇2 = 𝜇3 = 𝜇4 Ha: Not all the population means are equal. H0: Not all the population means are equal. Ha: 𝜇1 = 𝜇2 = 𝜇3 = 𝜇4 H0: 𝜇1 = 𝜇2 = 𝜇3 = 𝜇4 Ha: 𝜇1 ≠ 𝜇2 ≠ 𝜇3 ≠ 𝜇4 Correct: Your answer is correct. Find the value of the test statistic. (Round your answer to two decimal places.) 2.53

Incorrect: Your answer is incorrect. Find the p-value. (Round your answer to four decimal places.) p-value = .08
