I need help with steps using minitab to factor these. Please do not solve without using minitab. Thank you.

Question 1: An electronics engineer is interested in the effect on tube conductivity of five different types of coating for cathode ray tubes in a telecommunications system display device. The following conductivity data are obtained Coating Type Conductivity 1 143 141 150 146 152 149 137 143 3 134 133 132 127 129 127 132 129 147 148 144 142 (a) Is there any difference in conductivity due to coating type. What is the p- value? Use a = 0.05. (b) Analyze the residuals from this experiment. (c) If there is a significant difference, perform a Tukey test. (d) Use the Kruskal-Wallis procedure with a = 0.05 to test for differences in means. Question 2: An article in the ACI Materials Journal describes several experiments investigating the rodding of concrete to remove entrapped error. A 3-inch x 6-inch cylinder was used, and the number of times this rod was used is the design variable. The resulting compressive strength of the concrete specimen is the response. The data are shown in the following table. Rodding Level Compressive Strength 10 1530 1530 1440 15 1610 1650 1500 20 1560 1730 1530 25 1500 1490 1510 (a) Is there any difference in compressive strength due to the rodding level? Use o = 0.05. What is the p-value? (b) Analyze the residuals from this experiment. (c) If there is a significant difference, perform a Tukey test
