The following data are from an experiment on carnations. The explanatory variable is the amount of inorganic bromine (micrograms per milliliter) in a plot of standard size. The response variable is the average number of flowers per carnation plant for the 30 plants grown in the plot. Which of the following statements is true? Bromine 3 4 Average No. 3.2 2.9 6 3.7 7 2.2 8 1.8 10 12 15 16 2.3 1.7 0.8 0.3 Select one: O a. The value of r is positive and the scatterplot shows that the average number of flowers per carnation increases as the amount of bromine increases. O b. The value of r is negative and the scatterplot shows that the average number of flowers per carnation decreases as the amount of bromine increases. O c. The value of r is positive and the scatterplot shows that the average number of flowers per carnation decreases as the amount of bromine increases. Od. The value of r is negative and the scatterplot shows that the average number of flowers per carnation increases as the amount of bromine increases.
