Assignment 7

1. Time Spent at Company vs Satisfaction Level

## 
##  Pearson's product-moment correlation
## 
## data:  hr$time_spend_company and hr$satisfaction_level
## t = -12.416, df = 14997, p-value < 2.2e-16
## alternative hypothesis: true correlation is not equal to 0
## 95 percent confidence interval:
##  -0.11668153 -0.08499948
## sample estimates:
##        cor 
## -0.1008661

2.Technical interpretation

The p-value is less than alpha (0.01), therefore we reject the Ho and conclude that there is a slight, negative correlation between time spent at the company and satisfaction level.

3.Non-Technical interpretation

As time spent at the company increases, satisfaction level decreases slightly.
