Question

Through the career services office, you have arranged preliminary interviews at four companies for summer jobs. Each company will either 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. a) List all the possible values of X b) 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.

Answer 1

Ans:

From the given data, through the vocation administrations office,you have organized priliminary interviews at four organizations for summer occupations.

What's more, X is the randoom varaiable equivalent to the aggregate number of follow-up meetings that you may have.

a) Let all the possible values of X:

Here we need to list all the conceivable qualities.

• The irregular variable X is eual to the quantity of follow up meeting. absolutely the meeting is from four organizations.
• The conceivable results of X will be X = { 0,1,2,3,4} five conceivable qualities.

b) Here the random variable is discrete or continious:  

• Since X can take esteems over the limited interims it's a discrete irregular variable.
• It can take up qualities among the five conceivable results and subsequently discrete.

c) Uniformly distribution might be appropriate as a model for this random variable :

• Uniformly distribution might not be appropriate as a model for this random variable,since every one of the results are not similarly likely.
• The result that no meeting calls from any of the organization isn't preffered among alternate results.
• Results are not similarly likely henceforth uniform conveyance can't be demonstrated for this arbitrary variable .
