Use the information below to answer the following question(s).

The Marseille Water Taxi ferries tourists from the harbor at Marseille, France, to the Frioul Islands in the Mediterranean Sea. The table below shows the number of passengers on the noontime ferry over seven randomly selected days along with the current ambient temperature in degrees Celsius.



Use the Marseille Water Taxi data to perform a hypothesis test to determine if the population correlation coefficient is more than zero using α = 0.05.

For a one-tail test with α = 0.05 and 6 - 2 = 4 degrees of freedom, tα = 2.132. Because t = 1.84 is less than tα = 2.132, we fail to reject the null hypothesis. Based on our sample, we cannot conclude that the population correlation coefficient between temperature and number of passengers is greater than zero and is, therefore, not statistically significant.
