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.
a. the length left parenthesis in minutes right parenthesis of the longest telephone call made in a day
b. whether someone in the household owns a smart phone
c. the number of cell phones in the household

A. The length (in minutes) of the longest telephone call made in a day - This data is numerical and continuous as the value is calculated by a measuring process.

B. Whether someone in the household owns a smart phone -  It is a categorical variable as this question can only be yes or no.

C. The number of cell phones in the household - It is a numerical variable which is discrete as counting is used to answer this.

We can define the continuous data as a data can take on any value(integer or decimal like your weight)

Discrete numbers are whole numbers or integers.
