- The Transform 66 Outside the Beltway project, scheduled to be completed late 2022, is an expansion of the current highway that will provide new travel choices for drivers and hopefully congestion relief from the Capital Beltway (I-495) to Gainesville for a 22.5 mile stretch. This 22.5 mile stretch of I-66 will go through both Fairfax County and Prince William County. VDOT had team members from the project reach out through a phone survey for a random selection of 3,500 residents from both Fairfax County and Prince William County. One question asked on the survey was “Do you feel that the new I-66 Express Lanes will bring congestion relief?” Of the Fairfax County residents surveyed, 1,642 agreed they thought that the expansion will bring congestion relief while only 1,576 of the Prince William County residents surveyed agreed with the statement. 1) What is a possible confounding variable that might have introduced sampling bias intothe results of the survey?

- Two professors at a local college developed a new teaching curriculum designed to increase students' grades in math classes. In a typical developmental math course, 55%of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 15 students enrolled, 11 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the α=0.1 level of significance? Complete parts (a) through (g).Ariatnam, Najafi, and Morones (Journal of professional Issues in Engineering Education andPractice, 2002) describe an overview of academies in horizontal directional drilling conducted totrain engineers and inspector for the California Department of Transportation. A pretest wasadministered on the first day prior to any instruction. Instruction and field experience wereprovided over a 3 day period, followed by a final test administered at the end of the last day.Although the average final test score of 75.27% was higher than the average pretest score of55.61%, the difference was not significant.a. Identify the type of the study described here.b. What is the purpose of administering the pretest?Trematodes of the species Euhaplorchis californiensis may infect the California kill fish, Fundulus parvipinnis. Researchers have observed that infected fish spend excessive time near the water surface, where they may be more vulnerable to bird predation. Researchers set up an experiment in a large outdoor tank that stocked with three kinds of killifish, uninfected, lightly infected, and highly infected, and recorded the number of fish that is eaten by birds. State the null and alternative hypothesis
- The Department of Natural Resources (DNR) received a complaint from recreational fishermen that a community was releasing sewage into the river where they fished. These types of releases lower the level of dissolved oxygen in the river and hence cause damage to the fish residing in the river. An inspector from the DNR designs a study to investigate the fishermen’s claim. Fifteen water samples are selected at locations on the river upstream from the community and fifteen samples are selected downstream from the community. The dissolved oxygen readings in parts per million (ppm) are given in the following table.Upstream 5.2 4.8 5.1 5.0 4.9 4.8 5.0 4.7 4.7 5.0 4.6 5.2 5.0 4.9 4.7, Downstream 3.2 3.4 3.7 3.9 3.6 3.8 3.9 3.6 4.1 3.3 4.5 3.7 3.9 3.8 3.7 a.In order for the discharge to have an impact on fish health, there needs to be at least a 0.5 ppm reduction in the dissolved oxygen. Do the data provide sufficient evidence that there is a large enough reduction in the mean dissolved oxygen…A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

As a state employee, professor Hong hasn’t seen a raise since... well, ever.Thus, an important criterion, in fact the most important criterion is to find an exoticregion that can be visited inexpensively. There are three states of nature that could impact costs in these five areas of interest. Professor Hong has determined the average cost per day to visit each region under each of the possible states of nature. This table, which should not be construed as actual vacation advice, appears below. (Remember they are costs. Lower is better. For example, the most optimistic case is the one with lowest cost.)
