What method would I use to reach the answer on questions like this on averages?

A botanist conducts a study to see if foxglove flowers grow better in soil with a pH level of 3 or 7. She randomly assigns 10 flowers to grow in soil with a ph level of 3 and another 10 to grow in soil with a pH level of 7. At the end of the study, she measures the height of the flowers and finds that foxglove plants in the pH level soil of 7 are 9 inches taller than those in the pH level soil of 3, on average. She runs 300 simulations of the data and concludes that the result was 9% likely to occur by random chance. What is the correct conclusion that the botanist should make? O The results are not statistically significant. They do not suggest that the ph level of the soil had any effect on foxglove plant growth. O The results are statistically significant. They suggest that soil with a ph level of 7 promotes more foxglove plant growth than soil with a pH level of 3. O The results are statistically significant. They do not suggest that the pH level of the soil has any effect on foxglove plant growth. O The results are not statistically significant. They suggest that soil with a ph level of 7 promotes more foxglove plant growth than soil with a pH level of 3. Question # 1
