. Some researchers have conjectured that stem-pitting disease in peach tree seedlings might be related to the presence or absence of nematodes in the soil. Hence, weed and soil treatment using herbicides might be effective in promoting seedling growth. Researchers conducted an experiment to compare peach tree seedling growth with soil and weeds using a single factor Herbicide treatment. The three levels of Herbicide treatment are:

A: Control (no herbicide)

B: Herbicide with Nemagone

C: Herbicide without Nemagone

The researchers randomly assigned 6 of the 18 seedlings chosen for the study to each treatment group. They treated soil and weeds in the growing areas for the three groups with the appropriate herbicide. At the end of the study period, they recorded the height (in centimeters) for each seedling. The researchers would like you to test their data to see if there is a difference in average seedling height for the three treatment groups. They also wish to know which groups were significantly different and which treatment is the best for producing the tallest seedlings. The data can be imported using the following code:

code:

height,group 66,A 67,A 74,A 73,A 75,A 64,A 85,B 84,B 76,B 82,B 79,B 86,B 91,C 93,C 88,C 87,C 90,C 84,C 

what type of test should we run in Rstudio?
