- Measurements of the elderly are given by playing a block building game to see how tall they can build a tower. One block-building experiment repeated one month later, gave us the times (seconds) of five pairs of participants' completion times. Test the claim that there is a difference between the two experiments. A. At 1%, use the Classical approach & conclude it. B. Use the P-value approach & conclude it. 1st Experiment (A) 35 28 29 26 29 2nd Experiment (B)33 27 27 27 23 . Computing for the estimate of standard error =8 P-value approach: Using the t-distribution, we find the p-value is equal to 0.3899 for the two-tailed test. 0.3899> significant level a/2=0.005, so, one must fail to reject. Additionally, there's not enough evidence to conclude a significant difference in the times between the two experiments.A video game developer is testing a new game on three different groups. Each group represents a different target market for the game. The developer collects scores from a random sample from each group. The results are shown in the table below. Round all answers to 4 decimal places. Group A Group B 101 151 108 149 98 160 107 112 111 126 Group C 101 109 198 186 160 a. What is the F Statistic? b. What is the p-value? c. At the 10% signific ce level, the scores among the ferent groups different? O Yes, there is enough evidence to show that the scores among the groups are statistically significant at the 10% level. O No, there is not enough evidence to show that the scores among the groups are statistically significant at the 10% level.Please assist.
