The supervisor of the company wants to findif the mean time taken by the new workers to learn on the new machine is different from 90 min. asample of 20 workers shows that it took an average of 85 min. It is known that the learning time forall new workers are normally distributed with population slandered deviation of 7 min .Find the p-value for the test that the mean learning time for the casting on the new machine is difference from90 min .what will your conclusion be if a =0.01?pls solve fastإضافة وصف ....¢Dв는☐

You run a publishing company and you are assessing your proofreaders. You hope that they can proofread an average of 1000 words per hour, an industry benchmark, If they average fewer than 1000 words per hour you will need to reconfigure the staffing. You test the proofreading times of a sample of 100 of the proofreaders and find the sample average words per hour is = whether the population mean words per hour is greater than 1000 with a 95% confidence level. The z-critical value for this test is Z = Zo.05 975 and the sample standard deviation is s = 600. Test 1.645. Show all your steps clearly and illustrate your answer with a graph. %3D
A man who moves to a new city sees that there are two routes he could take to work. A neighbor who has lived there a long time tells him Route A will average 5 minutes faster than Route B. The man decides to experiment. Each day he flips a coin to determine which way to go, driving each route 20 days. He finds that Route A takes an average of 45 minutes, with standard deviation 3 minutes, and Route B takes an average of 49 minutes, with standard deviation 5 minutes. Histograms of travel times for the routes are roughly symmetric and show no outliers. Complete parts a and b. (...) a) Find a 95% confidence interval for the difference between the Route B and Route A commuting times, (µÂ ¯ µÃ) - The confidence interval is (.). (Round to two decimal places as needed.)

The researcher would like to determine if these data provide convincing evidence that the true mean amount of time volunteers who were given training held their breath is greater than volunteers without training. Let μ1 = the true mean amount of time that volunteers who were given training held their breath and μ2 = the true mean amount of time that volunteers without training held their breath. What are the appropriate hypotheses?
