Twelve homemakers were asked to estimate the retail selling price of two models of refrigerators. Suppose their estimates of selling price are shown in the following table. Homemaker Model 1 ($) 1 2 3 4 5 6 7 8 9 10 11 12 840 950 930 Find the value of the test statistic. T = 900 800 820 910 880 1,100 690 810 930 Model 2 ($) 1,130 930 840 1,090 1,160 990 1,090 1,140 1,200 870 890 880 Use these data and test at the 0.05 level of significance to determine whether there is a difference between the two models in terms of homemakers' perceptions of selling price. State the null and alternative hypotheses. OH: Median price for model 1 - Median price for model 2 20 H₂: Median price for model 1 - Median price for model 2 < 0 OH: Median price for model 1 - Median price for model 20 H₂: Median price for model 1 - Median price for model 20 Ho: Median price for model 1 - Median price for model 2 = 0 H₂: Median price for model 1 - Median price for model 2 * 0 O Ho: Median price for model 1 - Median price for model 20 H₂: Median price for model 1 - Median price for model 2 = 0 O Ho: Median price for model 1 - Median price for model 2 ≤0 H₂: Median price for model 1 - Median price for model 2 > 0 Find the p-value.
