Below is a line graph of global average temperature changes based on a weighted average ofmeteorological stations worldwide from 1880 to 2013. The graph shows both yearly values aswell as five-year running mean differences from the average of the 1951 to 1980 period. 95%confidence intervals (in green) are shown for selected periods.a. How dose the black (yearly) line differ from the red (5-year running mean) line? Explainwhy you would expect that difference to occur.b. Describe the overall pattern seen in the plot and any important deviations from thatpattern. Suppose that global temperatures stayed the same or decreased somewhat for aten-year period. Would the overall pattern seen in the graph then give a differentappearance?

This question is from the textbook and I had raised a request as the graph was not visible in your solution. The Cambridge Study in Delinquent Development was under-taken in north London to investigate the links between criminal behavior in young men and the socioeconomic factors of their upbringing. A cohort of 395 boys was followed for about 20 years, starting at the age of 8 or 9. The following table shows the total number of criminal convictions by the boys between the start and end of the study.

A salon owner estimates the number of clients she is expecting during the festive season to be 20% during Monday to Wednesday, 20% on Thursday and 60% over the weekend. She therefore hires additional staff to assist during the weekend to meet the client demand. She however only observes 30% during Monday to Wednesday, 20% on Thursday and 50% over the weekend in the first week of December. The salon owner is uncertain whether she should reduce the planned staff for the December festive period due the observed trend or not. She conducts a statistical test at α = 0.05 to determine if the observed trend fits the expected trend. Which of the following statements is true? A. The conclusion of the test is that she should not keep the additional staff for the weekend. B. The df for this test is 3. C. The p-value is greater than α. D. The null hypothesis is that the observed trend is different to the expected trend. E. The test statistic is χ2 = 5.33.

The Beaver Creek Pottery Company sells bowls and mugs, hand-made by Native American artisans, at a craft store and through a Web site. Making these items requires a special type of clay and a large amount of individual person-hours, so for planning purposes, the company would like to forecast future demand, specifically through its Web site, which has increasingly become the primary source of sales. Following is the company’s Web site demand (in items sold) for the past 36 months: Develop a linear trend forecast model, an exponentially smoothed model (a = 0.20), and a 5-month moving average forecast model and indicate which one you think should be used to forecast Web site demand.
