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 1 2 3 4 5 6 7 8 9 10 11 12 Model 1 ($) 840 950 930 900 Find the value of the test statistic. T+ = 800 820 910 880 1,100 690 810 930 Model 2 ($) 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. O Ho: Median price for model 1 - Median price for model 2 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 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 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 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. (Round your answer to four decimal places.) p-value = State your conclusion. O Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference between the two models in terms of homemakers' perceptions of selling price. O Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the two models in terms of homemakers' perceptions of selling price. O Reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the two models in terms of homemakers' perceptions of selling price. ● Reject Ho. There is sufficient evidence to conclude that there is a significant difference between the two models in terms of homemakers' perceptions of selling price.
