Dаtа fоr twо independent nоrmаl samples can be found in the table. We want to check if the population variances are different. What is the output for this test at 5% significance level? n Mean Variance 14 29 22 14 17 36
Pleаse nоte thаt this questiоn cоnsists of six pаrts. You need to show all mathematical calculations/explanations to get the final answer. Just giving the answer without showing work may result in zero for the question. Consumer Reports has conducted a survey to see if there is an association between experiencing issues on vehicles and the origin of the vehicle manufacture. The survey asked consumers about the problems they had with their vehicle during the previous 12 months. The origin of the vehicle manufacturer was classified as Asia, Europe or USA. Below shown information is from 100 vehicles/consumers from each manufacture: Asia, Europe or USA. Any Issues Origin of the Manufacture Total Asia Europe USA Yes 12 21 17 50 No 88 79 83 250 Total 100 100 100 300 You have also been provided a partial MINITAB output. Write the null and alternative hypotheses to test if there is an association between the origin of the vehicle manufacture and potential issues. What is the degrees of freedom for the test? In the provided output, the expected cell count in "Asian vehicles with issues" is 16.67. Clearly show the mathematical calculation to obtain this value. In the output, contribution from each cell towards the final test statistic is displayed. According to the output, contribution from "Asian vehicles with issues" is 1.3067. Clearly show the mathematical calculation to obtain this value. Calculate the p-value for the test you formulate in part 2. Write the P value as a probability statement and then copy the numerical value of the p value from the provided output. Write the final conclusion in the context of the problem (use 5% significance level)
