A company would like to determine the relationship between: the time (in years) spent at the company and the employee’s hourly pay. The data for 5 employees are listed in the table below. Calculate and interpret the correlation coefficient r. Include a plot of the data in your discussion.
years (X) | hourly pay (Y) |
---|---|
5 | 25 |
3 | 20 |
4 | 21 |
10 | 35 |
15 | 38 |
a. Calculate the Pearson correlation coefficient for the data.
b. Use an appropriate 2-tailed hypothesis test (ɑ = .05) to determine whether this relationship is statistically significant.
c. Based on your calculations, what can we conclude about the relationship between the time spent at the company and hourly pay?
