How many different sittings are pos-sible in the following scenarios?(a) One of the chairs is identified as being the head of the table.(b) All chair positions are identical, so sittings are identified only according to therelative positions with each other. (Here it only matters who sits on one's rightand who sits on one's left.)

A college professor conducted a survey in order to assess how much money nursing majors spend on course material compared to all other majors. To do so, she selected a random sample of 34 students. Each student was classified as a nursing major or as a non-nursing major. They were then asked how much they spent on books and other materials required for their courses this semester. Here are parallel boxplots summarizing the responses: Based upon the boxplots, which of the following statements cannot be concluded? (A) The range of the distribution of the cost of course materials for nursing majors is about the same as that of non-nursing majors. (B) The maximum cost for non-nursing majors is greater than the median cost for nursing majors. (C) The variability of the cost of course materials for the middle 50% of nursing majors is greater than the variability of the middle 50% for non-nursing majors. (D) The median cost of course materials for nursing majors is over $300 more than…

Latoya has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via 60 Freeway. In order to determine which way she should travel on a daily basis, Latoya has recorded the travel times for samples of nine trips via the 10 Freeway and nine trips via the 60 Freeway. The following table gives the travel times (in minutes) for the eighteen trips. Travel times in minutes 10 Freeway 71, 70, 69, 67, 71, 67, 70, 71, 77 60 Freeway 76, 74, 78, 78, 68, 73, 75, 72, 72 Send data to calculator Send data to Excel Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.10 level of significance, that μ₁, the mean travel time via the 10 freeway, is different from μ2, the mean travel time via the 60 freeway? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round…
