Researchers counted the number of breeding sea turtles on various sections of beach property in Cancun every year. Nine randomly selected sections of beach were used. The following table shows the number of counted sea turtles for two successive years (2015 and 2016).

A B C D E F G H I

2015 62 54 36 42 61 76 84 75 43

2016 60 58 31 40 62 70 81 72 43

At the 5% significance level, can it be concluded that the number of breeding sea turtles in 2015 is different from the number of sea turtles in 2016? Formulate and test the appropriate hypotheses. Use the critical value approach. Assume the population of paired differences has a normal distribution. Clearly state and explain your conclusion within the context of the question.
