The scatter plot shows the number of pumpkins that have been picked on the farm during the month of october:

a scatter plot with points showing an upward trend with points that are moderately spread out from a line of best fit. the y axis is labeled number of pumpkins and the x axis is labeled days in october

part a: using computer software, a correlation coefficient of r = 0.51 was calculated. based on the scatter plot, is that an accurate value for this data? why or why not? (5 points)

part b: instead of comparing the number of pumpkins picked and the day in october, write a scenario that would be a causal relationship for pumpkins picked on the farm. (5 points)
