A researcher wants to determine the impact of soil type on the growth of a certain type of plant. She grows three plants in each of four different types of soll and measures the growth in inches for each pland after one month resulting in the data below. Use this file: Assignment 9g2 data FOR R a) What null hypothesis is the researcher testing if she runs an ANOVA with this data? O Soil 3 provides a lower mean growth for the plant than the other types of soil. The mean growth of the plant in each type of soll is the same. O The variability in growth of the plant in each type of soil is the same. O One type of soil has a higher mean growth for the plant than the others. O The mean growth of the plant is different in each type of soil. b) What is the SStrt for the ANOVA? Give your answer to at least three decimal places. ✓ c) What is DFerr for the ANOVA? 8 d) What is the value of the F statistic for the ANOVA? Give your answer to at least three decimal places. e) Using a 0.05 level of significance, what conclusion should the researcher reach? O There is not enough evidence to reject the claim that the mean growth of the plant is the same in each type of soil. O Soll 1 has a higher mean growth for the plant than the other types of soil. The mean growth of the plant is not the same for all soil types. O Soil 3 has a lower mean growth for the plant than the other types of soil. X
