Q3. What is a research hypothesis and why is it important to carry-out research? Differentiate between Type I and Type II error and give an example for each.
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). Source of Sum of Squares Degrees of freedom Mean Square F Ratio Variation Between Workers 138.667 Between Machines 11.08 Residual Errors Total 166.667
To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material. Manufacturer 1 2 3 25 34 15 31 32 14 29 37 18 27 33 17 a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use a = 0.05. Sum of squares, treatment = Sum of squares, error = Mean squares, treatment = mean squares, error = Calculate the value of the test statistic (to 2 decimals). The P-value is: Less than 0.01, between 0.01 and 0.025, between 0.025 and 0.05, between 0.05 and 0.10, greater than 0.10 What is your conclusion? b. At the a = 0.05 level of significance, use Fisher's LSD procedure to test for the equality of the means for manufacturers 1 and 3. What conclusion can you draw after carrying out this test?
In a construction site wheelbarrow is loaded by a worker. The total weight after loading of barrowand the loading time is recorded for ten of the cycles in a day randomly.a) Find the correlation coefficient between the time and weight of wheelbarrow.Sample variance of loading time is 303.29Sample variance of the weight is 272.78b) Assume that the loading time is normally distributed. Please find the mean of loading time with99% confidence interval using t distribution. Time to Load(s) Weight of Wheelbarrow(kg)172 76173 83179 95171 84193 94193 106156 60158 70188 90139 53

The accuracy of a census report on a city in southern California was questioned by some government officials. A random sample of 1215 people living in the city was used to check the report, and the results are shown below. Census Sample Result Ethnic Origin Percent Black 10% 123 Asian 3% 46 38% Anglo Latino/Latina 471 41% 505 Native American 6% 61 All others 2% 9. A USE SALT Using a 1% level of significance, test the claim that the census distribution and the sample distribution agree. (a) What is the level of significance? State the null and alternate hypotheses. O H: The distributions are the same. H: The distributions are different. O Ho: The distributions are different. H,: The distributions are the same. O Ho: The distributions are the same. H,: The distributions are the same. O Ho: The distributions are different. H: The distributions are different.
