An article in the IEEE Transactions on Components, Hybrids, and Manufacturing Technology (Vol. 15, No. 2, 1992, pp. 146-153) describes an experiment in which the contact resistance of a brake-only relay was studied for three different materials (all were silver-based alloys). The data are as follows: Alloy Contact Resistance 1 95 97 99 98 99 99 99 94 95 98 2 104 102 102 105 99 102 111 103 100 103 119 130 132 136 141 172 145 150 144 135 (a) Does the type of alloy affect mean contact resistance? Use a = 0.01. Calculate to 2 decimal places fo: i Is there evidence to suggest a difference in the mean contact resistance due to the type of alloy? No. (b) Use the Fisher's LSD analysis from Minitab to analyze the means of the five different types of allo Ves Intervals for (column level mean) - (row level mean): 2 [-13.58, 1.98] 3 [-50.88, -35.32] [-45.08, -29.52] Which of the following pair(s) of material types (all) have significant differences of contact resistance? (c) Find to 1 decimal place a 99% confidence interval on mean contact resistance for alloy 3.
