Needs help: Simple linear regression model
In a yearlong study of gas usage to heat a particular building, on 37 randomly selected days during the year, the average outside temperature was measured as well as the corresponding gas usage for a 24-hour period. The simple linear model E(y) = β0 + β1x, where x is the average outside temperature over a 24-hour period and y is the gas usage during that same time period, was fit to the data. The analysis is given below.Regression StatisticsMultiplier0.4804958R Square0.23087621Adj...

Consider the simple linear regression model: HARD1 = β0 + β1*SCORE + є, where є ~ N(0, σ). Note: HARD1 is the Rockwell hardness of 1% copper alloys and SCORE is the abrasion loss score. Assume all regression model assumptions hold. The following incomplete output was obtained from Excel. Consider also that the mean of x is 81.467 and SXX is 81.733.

Problem 6 Simple Linear Regression To the Internal Revenue Service, the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of...
