In each case, state the possible values of the random variable (a) The number of customers arriving at a bank between noon and 1:00 P.M (b) The time required to download a file from the Internet (a) Is the number of customers arriving at a bank between noon and 1:00 P.M. discrete or continuous? ariable is continuous. The possible values are x 20. 0 A. The random v O B. The random variable is continuous. The possible values are x-o 1, 2.0. ° C. The random variable is discrete. The possible values are x 20. 0 D. The random variable is discrete. The possible values are x-o 1, 2 (b) Is the time required to download a file from the Internet discrete or continuous? 0 A. The random variable is discrete. The possible values are t-1, 2, 3,-- The random variable is discrete. The possible values are t>0. The random variable is continuous. The possible values are t> 0. O B. ° C. D. The random variable is continuous. The possible values are t-1, 2, 3,

Explanation / Answer

(a) Correct option:

D. The random variable is discrete. The possible values are x = 0,1,2,..

EXPLANATION:

In discrete data, only a finite number of values is possible and the values cannot be subdivided meaningfully. here, the number of customers can be any one of x = 0,1,2,..

(b) Correct option:

C. The random variable is continuous. The possible values are t > 0.

EXPLANATION:

Continuous data can take infinite number of possible values within a selected range. Here, the time required to download a file can be anything greater than 0.
