When a dummy variable is included in a multiple regression model, the interpretation of the estimated slope coefficient does not make any sense anymore. a. True
b. False

b. False

Step-by-step explanation:

A dummy variable is a numerical variable used in regression analysis to represent values for categorical data by using value 0 (shows absence of particular category) or 1  (shows presence of particular category) .We cannot use categorical data to evaluate the slope coefficient (numerical value) until we convert them into dummies.

Hence, the given statement is absolutely false.

x/7.50 = 15

x= 7.50 / 15 divide

x = 2
