A set of n=4 pairs of X and Y value has SSx=6, SSy=18, and SP=9, for these data, what is the pearson correlation?

Manatees are large sea creatures that live along the Florida coast. Many manatees are killed or injured by powerboats. Below are data on powerboat registrations (in thousands) and the number of manatees killed by boats in Florida in the years 1977 to 1990 (how folks who collect these data know the number of manatees killed by boats is unclear to me). Is there any evidence that power boat registrations is related to manatee fatalities? Pearson correlation should be used for these data.

A set of n = 28 pairs of scores (X and Y values) has SSx = 70, SSY = 50, and SP = 21. Calculate the Pearson correlation for the scores. If your calculations involve multiple steps, wait until your final answer to round. Enter your final answer as a number rounded to 2 decimal places. If the number is negative, remember to include the negative sign.

The denominator of the Pearson correlation coefficient measures the extent to which two factors vary together. True False

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 0.965. Using x=0.10, test if the population correlation coefficient between the starting salary and the GPA of a university business graduate is greater than zero. Starting Salary $2,600 $2,900 GPA 3.1 3.4 What are the correct null and alternative hypotheses? O A. Ho: p0. H₁₂₁: p=0 $2,400 2.6 O C.
