THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
The model y = β0 + β1X1 + β2X2 + ε was fitted to a sample of 25 families in order to explain household milk consumption: where y = Milk consumption,in quarts,per week,x1 = Weekly income,in hundreds of dollars,and x2 = Family size.The least squares estimates of the regression parameters were b0 = -0.03,b1 = 0.05,and b2 = 1.1,with coefficient standard errors
= 0.02;
= 0.38.The total sum of squares and the error sum of squares were found to be 165.8 and 66.32 respectively.
-Find the adjusted coefficient of determination.
Histogram
A graphical representation showing a frequency distribution where the data is grouped into ranges and represented by bars.
Bar Chart
A graphical representation of data using bars of different heights or lengths to compare values across categories.
Ratio Scale
A quantitative scale of measurement that has a true zero-point and units of equal intervals, allowing for the comparison of absolute magnitudes of numbers.
Interval Scale
A type of measurement scale that represents both the order of data points and the exact differences between them, but without a true zero point.
