Question

Through the career services office, you have arranged preliminary interviews at four companies for summer jobs. Each company will ether ask you to come to their site for a follow-up interview or not. Let X be the random variable equal to the total number of follow-up interviews that you might have. List all the possible values of X. ls the random variable discrete or continuous? Do you think a uniform distribution might be appropriate as a model for this random variable? Explain briefly. The possible values of X are. (Use a comma to separate answers as needed. Type integers or simplified fractions.) The random variable X is A uniform distribution be appropriate as a model for the random variable X because the outcomes equally likely

Explanation / Answer

a)

The possible value of X is the number of follow ups interview. Interview were taken at four comapines, therefore X can have {0, 1, 2, 3, 4} as possible values.

b)

As the number of offers made represented by random variable is integer it is a discrete variable. it is no continuous variable.

It is discrete random variable as the values taken by it have finites interval

Therefore, the random variable X is discrete.

c)

No uniform distribution is not appropriate as the outcomes are not equally distributed.
