Given the following molecular formulas, determine the empirical formula of each compound: P4O10, SnCl2, N2O3, CH3CO2

Phosphine, PH3, a reactive and poisonous compound, reacts with oxygen as follows:4PH3(g) + 8O2(g) → P4O10(s) + 6H2O(g)If 9.2 moles of phosphine react with sufficient oxygen, how many moles of P4O10 should form? Test pack

What does a VIF of 3 indicate?

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. 

Which of these is the best definition of SSE?

Which of the following is NOT a characteristic of correlation, r?

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?
