A researcher was interested in the relationship between annual electricity bills ($000) of an office, average outside temperatureoCoC 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	0.82
R square	0.6724
Observations	95
	Coefficients	p-value	Lower 95%	Upper 95%
Intercept	1.53	2.38	0.16	3.99
Temperature	{tem}	0.02	0.16	1.83
Office size	4.01	0.01	2.1	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.
