A study was done to look at the relationship between number of vacation days employees take each year and the number of sick days they take each year. The results of the survey are shown below. Vacation Days 3 2 9 6 13 14 9 12 Sick Days 3 4 2 3 0 0 0 a. Find the correlation coefficient: r = Round to 2 decimal places. b. The null and alternative hypotheses for correlation are: Ho: 7 = 0 H1: 7 0 The p-value is: (Round to four decimal places) c. Use a level of significance of o = 0.05 to state the conclusion of the hypothesis test in the context of the study. O 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 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 an employee who takes more vacation days will take more sick days than an employee who takes fewer vacation days. O 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 vacation days . d. TH (Round to two decimal places) e. Interpret r : There is a 85% chance that the regression line will be a good predictor for the number of sick days taken based on the number of vacation days taken. There is a large variation in the number of sick days employees take, but if you only look at employees who take a fixed number of vacation days, this variation on average is reduced by 85% O 85% of all employees will take the average number of sick days. Given any group with a fixed number of vacation days taken, 85% of all of those employees will take the predicted number of sick days. f. The equation of the linear regression line is: (Please show your answers to two decimal places) g. Use the model to predict the number of sick days taken for an employee who took 4 vacation days this year. Sick Days = (Please round your answer to the nearest whole number.)
