An owner of a home in the Midwest installed solar panels to reduce heating costs. After installing the solar panels, he measured the amount of natural gas used y (in cubic feet) to heat the home and outside temperature x (in degree days, where a day's degree-days are the number of degrees its average temperature falls below 65 degrees F) over a 23-month period. The software used to compute the least-squares regression line (ŷ = 85 + 16x) says that...

Help. Stuck on these last two! Will give a THUMBS UP for correct answers! :) 85. V MY NOTES A study of class attendance and grades among first-year students at a state university showed that in general students who attended a higher percent of their classes earned higher grades. Class attendance explained 2 = 36% of the variation in grade index among the students. What is the numerical value of the correlation between percent of classes attended and grade index?...
For several years, many utilities have employed regression analysis to forecast monthly utility usage by residential customers using weather forecasts, the number of holidays, the number of days in the month, and other factors. For example, the Connecticut Department of Public Utility Control (CDPUC) has determined that regression, properly used, can accurately predict natural gas usage Most public gas utilities serving Connecticut have reported levels of accuracy from 4% to 10% using regression. One company, Dominion Natural Gas Company of...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
