For each of the following variables, determine whether the variable is categorical or numerical. If the variable is numerical, determine whether the variable is discrete or continuous. In addition, determine the measurement scale a. Number of cellphones in the household b. Whether there is a high-speed Internet connection in the household c. Distance (in miles) from a person's house to the nearest store d. Number of text messages exchanged per month e. Time in hours spent exercising per week a. Number of cellphones in the household is what kind of variable? A. This variable is a categorical variable that is ordinal-scaled. B. This variable is a discrete numerical variable that is interval-scaled. C. This variable is a continuous numerical variable that is interval-scaled. D. This variable is a continuous numerical variable that is ratio-scaled. E. This variable is a categorical variable that is nominal-scaled. F. This variable is a discrete numerical variable that is ratio-scaled. b. Whether there is a high-speed Internet connection in the household is what kind of variable? A.
