Rosa is testing whether a fertilizer can cause a pea plant to grow more pods. She uses the fertilizer on a group of 30 plants and also grows a group of 30 plants with no fertilizer. The table includes the data that she collected. Mean number of pods A B C Rosa creates a sampling distribution for the difference in mean scores. The distribution is normal with a mean of 0 and a standard deviation of 10. Which TWO statements describe Rosa's results? The difference between the number of pods for fertilized plants and unfertilized plants is 0. The difference between the numbers of pods for fertilized plants and unfertilized plants is 19 pods. The difference between the numbers of pods for fertilized plants and unfertilized plants is -19 pods. 95% of the differences of means in the sampling distribution are between -1.96 and 1.96. The results are significant. 95% of the differences of means in the sampling distribution are between -19.6 and 19.6. The results are not significant. D Fertilizer E 129 No Fertilizer 110
