Data is available on the characteristics listed below for various cereals. Each of these cereals has been given a rating between 0 and 100. The output from a regression model to predict the Rating based upon the other characteristics of the cereal is provided. Calories: The number of calories in a serving. Protein: The amount of protein is a serving. Fat: The amount of fat in a serving. Fiber: The amount of fiber in a serving Sugars: The amount of sugar in a serving Potass: The amount of Potassium in a serving Vitamins: The percent of required daily vitamins in a serving.
The model that was estimated can be written as:
Y is the rating and the X's correspond to the input variables. For this data test the null hypothesis that . In other words, test the hypothesis that the coefficients for all the X's are equal to zero.
