The following table gives information on the amount of sugar (in grams) and the calorie count in one serving of a sample of 13 varieties of Kellogg's cereal. Sugar (grams) 4 15 12 11 8 7 14 20 1 13 Calories 120 200 120 | 110 100 80 190 || 90 120 | 190 | 190 || 110 | 120 The pledictive regression equation of the number of calories on the amount of sugar is y = 91.636+ 4.730x, where x is amount of sugar (in grams) and y is calories. Calculate the predicted calorie count for a cereal with 16 grams of sugar per serving. Round your answer to the nearest integer. calories the tolerance is +/-2%
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
