A surf shop surveyed 100 customers about the number of items purchased and the length of time spent shopping in the store. Classify the random variables from the survey. A) Number of items, discrete; total time, continuous B) Number of items, continuous; total time, discrete C) Number of items, continuous; total time, continuous D) Number of items, discrete; total time, discrete E) Unable to determine from information given

Using the concept of continuous and discrete variables, it is found that the correct option is:

In this problem:

You can learn more about continuous and discrete variables at link

Step-by-step explanation:

Discrete variable assume a finite number of values. It can easily be counted. Continuous variable assumes an infinite number of values. It cannot be easily counted. It is mostly measured. Considering the given scenario, we can see that the number of items purchased customers can easily be counted. The length of time spent shopping can take an infinite set of values within a given range, thus it cannot be counted.

Therefore, the classification for the random variables from the survey is

A) Number of items, discrete; total time, continuous

this answer is !
