Essay

Pop-up coffee vendors have been popular in the city of Adelaide in 2013. A vendor is interested in knowing how temperature (in degrees Celsius) and number of different pastries and biscuits offered to customers impacts daily hot coffee sales revenue (in $00's).
A random sample of 6 days was taken, with the daily hot coffee sales revenue and the corresponding temperature and number of different pastries and biscuits offered on that day, noted.
Excel output for a multiple linear regression is given below:  Coffee sales revenue  Temperature  Pastries/biscuits 6.52571017135.53054.53563.540328915\begin{array} { | c | c | r | } \hline \text { Coffee sales revenue } & \text { Temperature } & \text { Pastries/biscuits } \\\hline 6.5 & 25 & 7 \\\hline 10 & 17 & 13 \\\hline 5.5 & 30 & 5 \\\hline 4.5 & 35 & 6 \\\hline 3.5 & 40 & 3 \\\hline 28 & 9 & 15 \\\hline\end{array}  SUMMARY OUTPUT  Regression Statistios  Multiple R 0.87 R Square 0.75 Adjusted R Square 0.59 Standard Error 5.95 Observations 6.00 ANOVA dfSSMSF Significance F Regression 2.00322.14161.074.550.12 Residual 3.00106.2035.40 Total 5.00428.33 Coeffients  Standard Error  tStat  P-value  Lower 95% Upper 95% Intercept 18.6837.880.490.66101.88139.24 Temperature 0.500.830.600.593.152.15 Pastries/biscuits 0.492.020.240.825.946.92\begin{array}{|l|r|l|l|l|l|l|}\hline \text { SUMMARY OUTPUT } & & & & & & \\\hline \text { Regression Statistios } & & & & & & \\\hline \text { Multiple R } & 0.87 & & & & & \\\hline \text { R Square } & 0.75 & & & & & \\\hline \text { Adjusted R Square } & 0.59 & & & & & \\\hline \text { Standard Error } & 5.95 & & & & & \\\hline \text { Observations } & 6.00 & & & & & \\\hline \\\hline \text { ANOVA } & & & & & \\\hline & {d f} & SS & M S & F & \text { Significance } F \\\hline \text { Regression } & 2.00 & 322.14 & 161.07 & 4.55 & 0.12 \\\hline \text { Residual } & 3.00 & 106.20 & 35.40 & & \\\hline \text { Total } & 5.00 & 428.33 & & & \\\hline \\\hline & \text { Coeffients } & \text { Standard Error } & \text { tStat } & \text { P-value } & {\text { Lower } 95 \%} & {\text { Upper } 95 \%} \\\hline \text { Intercept } & 18.68 & 37.88 & 0.49 & 0.66 & -101.88 & 139.24 \\\hline \text { Temperature } & -0.50 & 0.83 & -0.60 & 0.59 & -3.15 & 2.15 \\\hline \text { Pastries/biscuits } & 0.49 & 2.02 & 0.24 & 0.82 & -5.94 & 6.92 \\\hline\end{array} Test the significance of the coefficient on Pasties/biscuits against a two tailed alternative.
