How you would use the concept of probabilities to apply to profiles for hiring more satisfied individuals? Job Satisfaction is an attitude about one's job. It may be measured globally or via facets (e.g., intrinsic / extrinsic). However, job satisfaction is a post hoc phenomenon. Using "profiles" developed via the DataSet to predict job satisfaction is not feasible. Further, the only variables you could use would be gender, age, department, position. To say, for example, that salaried females between 22-49 years of age and working in IT are more likely to be satisfied says noting about potential hires. It probably says more about the way the department is managed and the resources available to accomplish tasks. Finally, unless job satisfaction is a performance criterion, it would most likely be illegal to use this concept.

Other ways that probability is used in business (Feel free to use the Business Source Elite Database in the Cybrary as a resource to research how probability is used in business).

Begin your email to AIU by first providing an overview of the database, i.e., a story.

Include the following pieces of information.

Part I

a) What is the gender distribution (%females and %males)?
b) What is the "tenure with company" distribution by gender?
c) What % of the survey participants are in each department?
d) What is the mean overall satisfaction by gender?
Part II

Keeping in mind that in this email you are going to try to apply probabilities to profile hiring more satisfied individuals, discuss the following in your email.

a) If we choose a person at random from this database: - What is the probability that this person will be female?

If we choose a person at random from this database: -What is the probability that this person will be between 22 and 49 years old?

If we choose a person at random from this database: -What is the probability that their overall job satisfaction is 4.7 or lower?

b) If we choose a person at random from this database: -What is the probability that this person will be a male in the information technology department?

If we choose a person at random from this database: -What is the probability that this person will be an hourly employee whose intrinsic satisfaction is 6 or more?

c) Calculate the correlation between age and tenure with the company. Explain your results.

Part III

In your email you need to also address other ways that probability is used in business.

  • "Your solution, looks excellent. I recognize things from previous chapters. I have seen the standard deviation formula you used to get 5.154. I do understand the Central Limit Theorem needs the sample size (n) to be greater than 30, we have 100. I do understand the sample mean(s) of the population will follow a normal distribution, and that CLT states the sample mean of population is the population (mean), we have 143.74. But when and WHY do we use the standard deviation formula where you got 5.154. WHEN & Why use standard deviation of the sample mean. I don't understand, why don't we simply use the "100" I understand that standard deviation is the square root of variance. I do understand that the variance is the square of the differences of each sample data value minus the mean. But somehow, why not use 100, why use standard deviation of sample mean? Please help explain."
