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.

A student interested in Finance was interested in predicting sales ($M) based on assets ($M). She looked at data from 97 companies. She found the following equation.  yhat = 648.43 + 0.95x One of the companies had assets of [x1] and a sales of [obsy]. Find the residual and round to two decimal places. (Remember to include the negative sign if appropriate.) 

Suppose that you wanted to predict college GPA based on high school GPA, number of extracurricular activities, and SAT score.    What would be the appropriate null and alternative hypothesis for the F test?

A researcher was interested in estimating the literacy rate for a country based on the number of newspapers sold (per 1000 people), the number of radios (per 1000 people), and the number of TV sets (per 1000 people).  They found the following output from JMP.  (n = 20)  Predictor Coef SE Coef T p-value constant   0.51486   0.09368  5.50 0.002 newspaper   0.0005421  0.0008653  0.63 radios -0.0003535  0.0003285 -1.08 television sets  0.001988  0.001550  1.28   Which of the following is the p-value for newspaper?

A sociologist wants to predict the birth weight(ounces) of babies based on the weight of the mother and if the mother smoked (0 if non-smoker and 1 if a smoker).  She used data from the San Francisco Bay area that included 1,236 mothers from 1960 – 1967.   Interpret “-8.67”.
