Satisfaction level VS. Avg monthly hours

## 
##  Pearson's product-moment correlation
## 
## data:  emp$satisfaction_level and emp$average_montly_hours
## t = -2.4556, df = 14997, p-value = 0.01408
## alternative hypothesis: true correlation is not equal to 0
## 95 percent confidence interval:
##  -0.036040356 -0.004045605
## sample estimates:
##         cor 
## -0.02004811

Technical Interpretation

P-Val is greater than .01. This means if we are using an alpha of .01 we would accept the null hypothesis and reject that these variables have a weak negative correlation.

Non-Technical Interpretation

There is no Signifigant relationship between Satisfaction level and Avg Monthly Hours Worked

Satisfaction level VS. Last Evaluation

## 
##  Pearson's product-moment correlation
## 
## data:  emp$satisfaction_level and emp$last_evaluation
## t = 12.933, df = 14997, p-value < 2.2e-16
## alternative hypothesis: true correlation is not equal to 0
## 95 percent confidence interval:
##  0.08916727 0.12082195
## sample estimates:
##       cor 
## 0.1050212

Technical Interpretation

The P-Value is extremely small, H0 is rejected, which means that there is a correlation of .105 which is a very weak positive correlation

Non-Technical Interpretation

As Last evaluation Increases so do Satisfaction levels slightly

Satisfaction level Vs. Number of Projects

## 
##  Pearson's product-moment correlation
## 
## data:  emp$satisfaction_level and emp$number_project
## t = -17.69, df = 14997, p-value < 2.2e-16
## alternative hypothesis: true correlation is not equal to 0
## 95 percent confidence interval:
##  -0.1586105 -0.1272570
## sample estimates:
##        cor 
## -0.1429696

Tecnical Interpretation

There is an extremely small p-Val so the null hypothesis is rejected.The correlation is negative and weak

Non-Technical Interpretation

As The number of projects go up Satisfaction levels drop slightly

Last Evaluation Vs. Avg Monthly Hours

## 
##  Pearson's product-moment correlation
## 
## data:  emp$last_evaluation and emp$average_montly_hours
## t = 44.237, df = 14997, p-value < 2.2e-16
## alternative hypothesis: true correlation is not equal to 0
## 95 percent confidence interval:
##  0.3255078 0.3538218
## sample estimates:
##       cor 
## 0.3397418

Technical Interpretation

Null hypothesis is rejected due to extremely small p value. Correlation of .3397 is accepted a weak/moderate positive correlation.

Non-Technical Interpreatation

A higher last evaluation is found to increase Avg Monthly Hours
