A researcher was interested in the relationship between annual electricity bills ($000) of an office, average outside temperature °C and office size (square metres). A random sample was selected, and data collected. EXCEL was used to create a multiple linear regression, with a portion of the output provided here: Regression statistics Multiple R R square Observations Intercept Temperature Office size 0.84 0.7056 51 Coefficients 1.15 {tem} 3.01 p-value 3.15 0.04 S 0.03 Lower 95% 0.16 0.1 2.65 Upper 95% 3.99 1.11 5.05 What is the upper confidence limit for a 95% confidence interval for the coefficient of Office Size? Please give your answer correct to two decimal places and do NOT include units in your answer.
