From interviews with 18 tourists who have stayed at Great Barrier Reef holiday resorts, data on the size of the group, the length of stay in the region (measured in days), the number of resorts visited and the number of holidays they have had in the last five years. The partially completed ANOVA table for the regression model using all the variables on which data was collected is given below:

 Source of variation df SS MS Regression A D F Error B E 352.7 Total C 11858.6

Assume that a 0.005 level of significance has been adopted for the test of the overall significance of the relationship.

1. Calculate the test statistic, reporting your answer correct to two decimal places.

2. Use the tables in the text to determine the critical value for the test.

3. Is the null hypothesis rejected for this test? Type yes or no.

4. Hence, on the basis of this test, is at least one of group size, the length of stay, the number of resorts visited and the number of holidays taken related to average daily expenditure by tourists? Type yes or no.
