There are three different ways I can go to work in the morning. I want to see if there is a difference in the distributions of travel-times between the three different ways. The sample data is depicted below. I claim there is a difference in mean travel times between the three different routes. I cannot guarantee that the distributions of these travel times are Normal.     Travel Time in Minutes Interstate 22 22 21 23 22 21 Route 15 22 18 20 18     Back Roads 19 19 18 19 22   (a) Enter the rank values in the same order as in the original sample.   Interstate             Route 15         Back Roads           (b) Give the value of the test statistic:  (c) Test my claim at the 10% significance level.Enter the critical value: There is sufficient evidence to conclude that the population means are not equal.YesNo (d) Does your conclusion change at the 5% significance level?YesNo

What would the alt and null hyp. be? How would I calculate/understand cohen d? I believe the sig. (two tailed) is .003....how to determine significance?

A De Anza student decided to determine whether the percent of men who participate in sports at De Anza College is higher than the percent of women who participate in sports at De Anza College. Out of 67 women, 12 said they participate in sports. 13 of the 45 men surveyed said they participate in sports. a. ) What are the type I and type II errors? Explain them in the context of this problem.b. ) Describe the sample statistics in words. What is the distribution of the sample statistic? Explain why you used this distribution.Can someone please help me make sense of these questions?

A hospital has a main campus and three satellite locations. Management wants to reduce waiting time for ER cases. A random sample of 11 ER cases at each location was selected, and the waiting time was measured. Excel.) Complete parts (a) through (d) to determine if there is statistical evidence of a difference in the mean waiting times betweeen the four locations. a. State the two hypotheses. Choose the correct answer below. O B. Ho: H1 = H2 = ••• = H4 H;: 41 H2# • • • # µ4 O A. Ho: H1 =H2 = ••• = H4 H;: Not all H are equal (where j= 1,2,.4) OC. Họ: H1 = H2 = • •• = H1 H;: 41 # H2# • •• #H11 D. Ho: H1 = H2= • •• - H11 H;: Not all H; are equal (where j= 1,2,.,11) b. At the 0.05 level of significance, state the test statistic.
