You are a manufacturing engineer with a machine company. The company buys 55 gallon drums of pentrating lubricant. These drums are expensive. The weight of a drumshould be 400 pounds. As a new engineer you have been asked to use your Six Sigma Green Beitto determine if these barrels really weigh 400 pounds. Your company knows statistics and has asked you to use a hypothesis test atthe 5% level of significance. You select 9 barreis at random and weigh. You find the average weight of the barrels to be 398 pounds with a standard deviation of 22 pounds.Answer the followingYour null hypothesis is equal to what?(no decimals)What is the hypothesis test?(greater than or less than)What is your sample size?(no decimal)What is your sample mean?(no decimal)What is your sample standard deviation?(one decimal)What is your test statistic (T test?two decimais)What is your crntical value?(two decimaln)What is your p-value?(wo decimals)What is your conclusion?(reject or fail to rejectDoes this statistically prove that the lubricant weight is less than 400 pounds?(yos or no

Solution: Claim: The lubricant weight is less than 400 pounds. The null hypothesis is Ho:μ=400…

Mr Sharma wants to assess if the time taken to complete a job by 3 different machines is significantly different at 5%. As he thought the worker may also impact the time taken hence he used 4 different workers and randomly assigned them to machine and jobs such that each worker works on each machine. State the hypothesis for Mr Sharma. Complete the table below and help Mr Sharma get the answer of the questions).

Three restaurant servers are competing for Employee of the Month. The table below shows the number of customers each server waited on either at curbside pickup or counter service. The employee who waits on the most customers will be the Employee of the Month. Do the data in the table provide evidence that Server B is responsible for more than of all the customers at this restaurant? Justify your answer using statistical inference (that is, complete each bullet listed below). Server A Server B Server C TOTAL Number of Curbside Customers 21 15 15 51 Number of Counter Customers 39 50 17 106 TOTAL 60 65 32 157 Answer each of the bullets below. You may hand write your answer, or type in the space provided. Write the null and alternative hypothesis. Define the parameters used in the hypothesis. Check to make sure the conditions are met to assume a normal distribution. Write the formula for the test statistic that would be used. Use appropriate notation. Evaluate…

7:39 Done A myopenmath.com AA Lindsey and Andrea began arguing about who did better their tests, but they couldn't decide who did better given that they took different tests. Lindsey took a test in Social Studies and earned a 75.2, and Andrea took a test in Math and earned a 68.1. Use the fact that all the students' test grades in the Social Studies class had a mean of 73.7 and a standard deviation of 11.4, and all the students' test grades in Math had a mean of 60.4 and a standard deviation of 10.8 to answer the following questions. a) Calculate the z-score for Lindsey's test grade. = Z b) Calculate the z-score for Andrea's test grade. c) Which person did relatively better?

I understand how the level of signficance = 1.96 and I understand: Ho:μ=5 - Ha:μ<5 But I need help understanding how to calculate the test statistic. I know we have a sum of 93 with a sample size of 28 but how do you come to the conclusion for the test stastisic and how do you figure out whether you have enough proof to accept or reject the claim? Thank you.
