Twenty onion seeds were randomly assigned in pairs to two different types of soil Soil A and Soil B The first pair of seeds were planted nearest to a window and received plenty of sunlight The next two seeds were planted in each type of soil and were placed 6 inches away from the window The third pair of seeds were planted in each type of soil and were placed 1 foot away from the window and so on After 6 months the onions were harvested and their diameters were measured in centimeters The dotplot below shows the mean difference Soil A Soil B in diameter for each pair of onion seeds 2 2 1 5 1 0 5 0 0 5 1 1 5 Difference Soil A Soil B in diameter cm Select one Which of the following accurately describes what the dotplot reveals about whether Soil A tends to produce larger onions than soil B O a It does not appear that Soil A tends to produce larger onions than Soil B because the sample size is too small O b It does not appear that Soil A tends to produce larger onions than Soil B because the distribution of differences is skewed fairly symmetric O e O c It does not appear that Soil A tends to produce larger onions than Soil B because 5 of the differences are positive O d It does not appear that Soil A tends to produce larger onio than Soil B because only 5 of the differences are positive It does not appear that Soil A tends to produce larger onions than Soil B because 1 of the difform
