Answer #1

The five examples of a discrete random variable are

1) Number of students in a class

2) The number of tails flipped in 4 trials

3) Number of customers who visit a showroom in a day

4) Number of House in a certain block

5) Number of fishes caught on a fishing trip

6) Counting the number of petals of flower

They have to be in whole number as from all the examples we can conclude that they are all in whole numbers as number of students can't be in fraction similarly holds for all. As discrete variable is counting the number of events which can only be whole numbers.

State whether the actual data are discrete or​ continuous, and explain why. The number of phone calls made each day by the sales representative of a company. ​Continuous, because the numbers can have any value within some range of values. ​Discrete, because only counting numbers are​ used, and no values between the counting numbers are possible.

Which of the following statements is false? It is not possible for a continuous variable to have a finite number of values. If a random variable can take on all of the possible values between 2 and 4, then it is a continuous variable. It is possible for a discrete variable to have an infinite number of possible values. A discrete variable is always represented by whole numbers.
