Listed below is the multiple regression equation for predicting Y by X1 through X4. Y = Sales per month X1= Amount spent on printed ads X2= Amount spent on text messages X3= Amount spent on radio ads X4= Amount spent on customer service support   There are a total of n=56 observations used in the analysis.   Y-hat =  12.34 + 1.55 X1 + 0.22 X2 +1.45 X3 + 0.612 X4   The F test statistic equals 2.7. What is the p-value for the overall F test? Round to three decimal places.
