A Study Has Recently Been Conducted by a Major Computer

question 3

True/False

A study has recently been conducted by a major computer magazine publisher in which the objective was to develop a multiple regression model to explain the variation in price of personal computers. Three quantitative independent variables were used along with one qualitative variable. The qualitative variable was coded 1 if the computer included a monitor, 0 otherwise. The following computer printout shows the final output. Based on this information, it is possible to determine that 4 of the PCs in the data set did not have a monitor included.
