Concept explainers

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 p…

Refer to the original question, but use this data instead:use this data instead: Max 2500E + 2100L s.t. 6E+4L <= 2400 L <= 250 3E + 4L <= 1500 E,L >= 0 a. What is the optimal solution value for E (number of units of the EZ-Rider)?b. What is the optimal solution value for L (number of units of the Lady-Sport)?c. What is the profit?
In a statistics course, a linear regression equation was computed to predict the final exam score from the score on the midterm exam. The equation of the least‑squares regression line was ?̂ =10+0.9?, where ?y represents the final exam score and ?x is the midterm exam score. Suppose Joe scores an 80 on the midterm exam. What would be the predicted value of his score on the final exam?
What is the regression to find a quadratic model for the data? The answer above does not mae sense.
