One is to go via the 10 Freeway, and the other is to go via 60 Freeway. Inorder to determine which way she should travel on a daily basis, Susan has recorded the travel times for samples of ten trips via the 10 Freeway and ten tripsvia the 60 Freeway. The following table gives the travel times (in minutes) for the twenty trips.Travel times in minutes10 Freeway 70, 70, 70, 71, 74, 65, 75, 67, 72, 6660 Freeway 72, 74, 73, 74, 78, 75, 73, 69, 74, 70Send data to calculatorSend data to ExcelAssume that the two populations of travel times are normally distributed and that the population variances are equal.

Use the following information for the question. A group of home gardeners want to test whether the type of soil used to grow heirloom tomatoes has an effect on the number of tomatoes harvested. Gardeners randomly assigned tomato plants to be grown in soil with no fertilizer, commercial plant food, and homemade compost. All other growing conditions were kept the same. Forty plants were assigned to each group. At the end of the growing season the number of tomatoes harvested was counted. Assume that all other conditions for the ANOVA test have been met. One-way ANOVA F=0.762135 P=0.5202354 Factor df-2 SS=710.349206 MS=355.174603 Using the test results provided, test the hypothesis that soil treatment affects the number of tomatoes harvested. Use a significance level of 5%. Choose the correct decision regarding the null hypothesis and correct conclusion. O Reject Ho. We can conclude that the treatment of the soil affects the number of heirloom tomatoes harvested. O Reject Ho- We can…
