a Find the correlation coefficient:
b. The null and alternative hypotheses for correlation are:
The p-value is
(Round to four decimal places)
c. Use a level of significance of 0.05 to state the conclusion of the hypothesis test in the context of the study.
There is statistically insignificant evidence to conclude that there is a correlation between the number of
vacation days taken and the number of sick days taken Thus, the use of the regression line is not
appropriate.
There is statistically significant evidence to conclude that there is a correlation between the number of
vacation days taken and the number of sick days taken Thus, the regression line is useful
There is statistically significant evidence to conclude that an employee who takes more vacation days will
take fewer sick days than an employee who takes fewer racation days
