. The following data represent the running time of mushroom substrate bag filling machine to finish certain number of bags by two different machines: Machine Time (seconds) 102 90 95 100 98 N 90 140 96 135 96 110 . Test the hypothesis that the average running time to fill certain number of bags by machine 2 exceeds the average running time of machine 1 by 10 seconds. Use a 0.05 level of significance and assume the distributions of times to be approximately normal. Further, assume that the variance of the two samples are significantly different. In testing the hypothesis, use the traditional method that involves the five steps. 1.) State the null and alternative hypothesis 2.) Determine the critical value and use the normal distribution curve to illustrate as to where the critical region and non-critical region is located. 3.) Compute the test statistic for this problem by choosing first the appropriate statistical test to be used. 4.) Provide the decision 5.) Interpret the result of the hypothesis testing
