<em>Comment on correlation coefficient</em>
The correlation coefficient (r) is the ratio of the covariance of x and y to the product of the standard deviations of x and y.

Step-by-step explanation:
Given that her hourly wage=$15.50 / hour
As she works 40 hours per week, so her weekly pay = 15.50 x 40 = $62/ week.
If she works 50 weeks each year, so her yearly pay = 62x50=$3100 /year.
Hence, her regular weekly pay is $62 and her annual salary is $3100.
