Step-by-step explanation:

I've already answered this question.

Answer/Explanation:

A. Fom the dattached diagram below showing the number of flowers that have bloomed in the garden in the month of March, we can infer that the trend shows a strong positive correlation. If we attempt to draw a straight line to connect some of the points on the plot, we would realized that we're going to be having a line that slopes upward, and also points are either on the line or are at least not far from the line drawn. Having a correlation coefficient or r = 0.98, we can assume that value to be accurate because the trend shows a positive correlation that is closer to a correlation coefficient of 1.

B. A scenario that would show a casual relationship for flowers in the garden is the comparison of the numbers of flowers in the garden and the quantity, in kg of a nutrient-rich fertilizer.
