Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume the orders are randomly selected from those included in the table. A B C D Order Accurate 310 262 247 144 Oder Not Accurate 35 55 33 17 If one order is selected,find the probability of getting an order from Restaurant A or an order that is accurate. Are the events of selecting an order from Restaurant A and selecting an accurate order disjoint events? a) The probability of getting an order from Restaurant A or an order that is accurate is (round to three decimal places as needed)
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.
1) Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume the orders are randomly selected from those included in the table.
| A | B | C | D | |
| Order Accurate |
310 | 262 | 247 | 144 |
| Oder Not Accurate | 35 | 55 | 33 | 17 |
If one order is selected,find the
