Researchers collected data on the numbers of hospital admissions resulting from motor vehicle crashes, and results are given for Friday the 6th and Friday the 13th in the same month. Use the Wilcoxon signed-ranks test to test the claim that the matched pairs have differen that come from a population with median equal to zero at a significance level of a=0.1. - X Fri. 6th 7 10 9 7 12 11 10 10 12 14 Fri. 13th 11 11 Click to view a table of critical values for the Wilcoxon signed-ranks test. 8 10 First define the null and alternative hypotheses.

Please help with the areas marked with an X 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   19 29 16   25 27 15   23 32 19   21 28 18 a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use . Sum of Squares, Treatment X Sum of Squares, Error X Mean Squares, Treatment X Mean Squares, Error X Compute the values below (to decimals, if necessary).     Calculate the value of the test statistic (to decimals)_______x_________.          b. At the level of significance, use Fisher's LSD procedure to test for the equality of the means for manufacturers and . Calculate Fisher's LSD Value (to decimals)______X______
