Does soil without nitrogen decrease the weight of worms compared with soil with nitrogen? the weight of 14 randomly selected worms is acquired, seven in soil with nitrogen and seven in soil without nitrogen. the mean weight of worms in soil without nitrogen was 35.3 micrograms whereas the mean weight of worms in soil with nitrogen was 45.3 micrograms. a researcher randomized the data over 100 trials, and the difference of means for each trial is shown in the dot plot below. what can the researcher conclude from this study?

A. The difference in weights is not significant because an original difference of means of 3 is not very likely

B. The difference in weights is significant because an original difference
of means of 3 is not very likely

C. The difference in weights is significant because an original difference of means of 3 is very likely

D. The difference in weights is not significant because an original difference of means of 3 is very likely
