Dave Fletcher, the general manager of North Carolina Engineering Corporation (NCEC), thinks that his firm’s engineer-ing services contracted to highway construction firms are directly related to the volume of highway construction business contractedwith companies in his geographic area. He wonders if this is reallyso, and if it is, can this information help him plan his operationsbetter by forecasting the quantity of his engineering servicesrequired by construction firms in each quarter of the year? Thefollowing table presents the sales of his services and total amountsof contracts for highway construction over the past eight quarters:   a) Using this data, develop a regression equation for predictingthe level of demand of NCEC’s services. b) Determine the coefficient of correlation and the standard errorof the estimate.

Suppose the closing price for the DJIA and the S&P 500 for 144 days in a certain year are as provided in the file closingprices3.xlsx. (a) Develop a scatter chart for these data with DJIA as the independent variable. What does the scatter chart indicate about the relationship between DJIA and S&P 500? The scatter chart indicates there may be a positive linear relationship between DJIA and S&P 500. The scatter chart indicates there may be no noticeable linear relationship between DJIA and S&P 500. The scatter chart indicates there may be a negative linear relationship between DJIA and S&P 500. (b) Develop an estimated linear…

A random sample (n-101) of adults were given a questionnaire to ask the question "How often do you use pain medication in one day?". Using the output, histogram, box-whisker plot, and the QQ Plot attached - check the assumption of normality for this data. PainNormalitylnformationoutputhistbox 210317.pdf 1. continuous 2.
