1. We want to know if the timing of the first blooms on Japanese Cherry trees is dependent on the coolness of the weather. The table below contains the average temperature in March (Celsius) and the day of April when the first blossom appeared for a 24-year time period. X = average temperature in March; y = day in April of first bloom y y 4.0 14 4.9 9 4.5 10 5.4 8 3.8 14 4.1 17 3.2 4.0 13 6.1 3 2.6 19 5.1 11 6.2 4.2 14 4.3 13 5.1 11 4.7 1.5 28 5.0 4.9 14 3.7 17 4.6 4.0 21 3.8 19 4.0 11 a) Graph the data. Look at your scatterplot – does this data set show a correlation? If so, what how would you describe the correlation (strength, direction)? Which function family would you use to describe this? b) Find the equation of the regression equation that would best describe this data. What is this equation? 3. 11 14
