Enrollment in a particular class for the last four semesters has been 120, 126, 110, and 130. Suppose a one-semester moving average was used to forecast enrollment (this is sometimes referred to as a naïve forecast). Thus, the forecast for the second semester would be 120, for the third semester it would be126, and for the last semester, it would be 110. What would the MSE be for this situation?

One technique to help people deal with phobias is to have them counteract the feared objects by using imagination to move themselves to a place of safety. In an experimental test of this technique, patients sit in front of a screen and are instructed to relax. Then, they are shown an image of the feared object. The patient signals the researcher as soon as feelings of anxiety reach a point at which viewing the image can no longer be tolerated. The researcher records the amount of time that the patient was able to endure looking at the image. The patient spends 2 minutes imaging a “safe scene” such as a tropical beach or a familiar room before the image is presented again. As before, the patient signals when the level of anxiety becomes intolerable. If patients can tolerate the feared object longer after the imagination exercise, it is viewed as a reduction in the phobia. The data in the table below summarize the times recorded for a sample of n-7 patients. Do the data indicate that…
- TABLE 2.5 Student teachers are trained to develop lesson plans, on the assumption that the writ- ten plan will help them to perform successfully in the classroom. In a study to assess the relationship between written lesson plans and their implementation in the class- room, 25 lesson plans were scored on a scale of 0 to 34 according to a Lesson Plan Assessment Checklist. The 25 scores are shown in Table 2.5. Use Tchebysheff's The- orem and the Empirical Rule (if applicable) to describe the distribution of these assessment scores. Lesson Plan Assessment Scores 26.1 26.0 14.5 29.3 19.7 22.1 21.2 26.6 31.9 25.0 15.9 20.8 20.2 17.8 13.3 25.6 26.5 15.7 22.1 13.8 29.0 21.3 23.5 22.1 10.2For the following line graph, State at least one type of conclusion that could be made from the data provided for the KPI. Suggest one other data source that would provide more information to make data-driven decisions. Explain what information that source would supply. I used the line graph btw. Examples: 1)The KPI webpage for South Texas College provides information on the proportion of graduates who find employment. According to the data, over the past five years, the proportion of graduates who find work has risen annually. Data on the percentage of students who are employed in their field of study after graduation, the percentage of students who are employed full-time after graduation, and the percentage of students who are satisfied with their job after graduation would also be useful in making decisions about post-graduation success. This information would shed light on the factors that are causing the rise in the proportion of graduates who find employment. 2)The…Chapter 11 2. Directions: Show all your work.
