Question

Delta wire prides itself on its efforts in the area of employee education.

Employee education can pay off in many ways. Discuss some of them. One payoff can be the renewed interest and excitement generated toward the job and the company. Some people theorize that because of a more positive outlook and interest in implementing things learned, the more education received by a worker, the less likely he or she is to miss work days. Suppose the following data represent the number of day’s sick leave taken by 20 workers last year along with the number of contact hours of employee education/training they each received in the past year. Use the techniques learned in this chapter to analyze the data. Include both regression and correlation techniques. Discuss the strength of the relationship and any models that are developed.

Answer 1

Data

Using Excel

data -> data analysis -> regression

y^ = 7.7455 - 0.0795 x

p-value of model = 0.0001 < alpha

hence the model is significant

r = -0.7732   {negative as slope is negative}

this means there is strong and negative relationship
