A university would like to describe the relationship between the GPA and the starting monthly salary of a graduate who earned a business degree from the university. The table shown below gives the monthly starting salaries for five graduates of the business school along with their corresponding GPAS. These data have a sample correlation coefficient, rounded to three decimal places, of 0.913. Using a0.05, test if the population correlation coefficient between the starting salary and the GPA of a university business graduate is greater than zero. Starting Salary $2, 500 $2.800 $2.500 $3,000 $2,300 GPA 3.2 3.4 2.7 3.6 25 What are the correct null and altemative hypotheses? OA H ps0 O B. H: p20 H, pco H, p>0 OC. H, pr0 H, p=0 O D.

Cuckoo birds are in the habit of laying their eggs in other birds' nest. The other birds adopt and hatch the eggs. The lengths (in cm) of cuckoo birds' eggs in the other species nests were measured and are in the table. Do the data show that the mean length of cuckoo bird's eggs is not all the same when put into different nests? Test at the 10% level.
