For each round, two measurements of the velocity were recorded using two different Question list K measuring devices, resulting in the following data. Complete parts (a) through (d) below. Observation 1 2 3 5 6 A 794.5 792.4 792.7 790.9 791.9 793.2 Question 1 804.3 791.1 798.2 786.7 792.8 792.3 Question 2 that the differences are approximately normally distributed with no outliers. Let d; = A; - Bj. Identify the null and alternative hypotheses. Question 3 Ho: Hd = 0 Hy: Hd # 0 Question 4 Determine the test statistic for this hypothesis test. to = -0.78 (Round to two decimal places as needed.) Question 5 Find the P-value P-value = 0.470 (Round to three decimal places as needed.) Question 6 What is your conclusion regarding Ho? Do not reject Ho. There is not sufficient evidence at the a= 0.01 level of significance to conclude that there is a difference in the measurements of velocity between device A and device B. Question 7 (c) Construct a 99% confidence interval about the population mean difference. Compute the difference as device A minus device B. Interpret your results. The lower bound is Question 8 The upper bound is. (Round to two decimal places as needed.) Question 9 More View instructor tip Help me solve this Get more help - Clear all Check
