- Explain how to choose the dependent and independent variables in regression analysis used for costestimationarrow_forwardIn a regression model if you drop one insignificant variable then a. R ^ 2 will increase and SSE also will increase . None R ^ 2 will decrease and SSE also will decrease . O d R ^ 2 will increase but SSE will decrease . O e R ^ 2 will decrease but SSE will increase .arrow_forwardUse the least squares regression line of this data set to predict a value. Meteorologists in a seaside town wanted to understand how their annual rainfall is affected by the temperature of coastal waters. For the past few years, they monitored the average temperature of coastal waters (in Celsius), x, as well as the annual rainfall (in millimetres), y. Rainfall statistics • The mean of the x-values is 11.503. • The mean of the y-values is 366.637. • The sample standard deviation of the x-values is 4.900. • The sample standard deviation of the y-values is 44.387. • The correlation coefficient of the data set is 0.896. The least squares regression line of this data set is: y = 8.116x + 273.273 How much rainfall does this line predict in a year if the average temperature of coastal waters is 15 degrees Celsius? Round your answer to the nearest integer. millimetresarrow_forward
