The results of an experiment comparing the cycle lengths of three different brands of washing machines (N=33) indicated an overall mean square error of 2.58. The researcher believes that the brands 1 and 2 may be the most different as they have mean cycles of 31.8 (n=12) and 35.9 (n=10). Using an alpha of 0.05, what would be the result of the Tukey-Kramer formula? O 0.64 O 3.82 O 3.49 O 1.49 O 1.70 A manufacturer of heaters wants to determine if the height of the heater warms a room more quickly. Four different heights were studied. The shortest heater group had n=12 with an average time to heat the room of 15.9 minutes. The tallest heater group had n=10 with an average time to heat the room of 17.3 minutes. Using an alpha of 0.01, MSE of 2.88, and N=44, what would be the q obtained for this problem? O 3.70 O 3.74 O 4.80 O 4.70 O 4.60 A manufacturer of heaters wants to determine if the height of the heater warms a room more quickly. Four different heights were studied. The shortest heater group had n=12 with an average time to heat the room of 15.9 minutes. The tallest heater group had n=10 with an average time to heat the room of 17.3 minutes. Using an alpha of 0.01, MSE of 2.88, and N=44, what would be the result of the Tukey-Kramer formula? O 2.41 O 2.01 O 1.40 O 4.70 O 1.24 A manufacturer of heaters wants to determine if the height of the heater warms a room more quickly. Four different heights were studied. The shortest heater group had n=12 with an average time to heat the room of 15.9 minutes. The tallest heater group had n=10 with an average time to heat the room of 17.3 minutes. Using an alpha of 0.01, MSE of 2.88, and N=44, would the research find evidence of a significant difference in these brands? O Yes, as the difference in the means is larger than the critical value O No, as the difference in the means is larger than the critical value O No, as the difference in the means is smaller than the critical value O Yes, as the difference in the means is smaller than the critical value O No, as the critical value is smaller than the overall sample size
