Use the data provided to perform a single factor ANOVA in R. (has to be in R or known as Rstudio)

Data description: This data describes the results of a study examining the effect that 'designer' oils' with a low n-6:n-3 fatty acid ratios had on the cardiovascular health of mice. The expectation was that mice fed with diets supplemented with 'designer' oils with low n-6:n-3 fatty acid ratios would result in improved cardiovascular health relative to mice fed with diets containing oils with high n-6:n-3 fatty acid ratios. All mice were fed an atherogenic diet (which promotes the formation of fatty plaques in the arteries), supplemented with either safflower oil as a control (25:1 n-6:n-3 fatty acid ratio), or a fish oil- or flaxseed oil-based 'designer oils', each with an approximate n-6:n-3 fatty acid ratio of 2:1. This was a completely randomized design, with 18 individually caged mice. Each mouse was randomly assigned to receive one of the three diets. Diets were administered for four weeks, then the mice were euthanized, and plasma cholesterol levels were measured (mmol/L). The higher the measured cholesterol level, the lower the cardiovascular health of the mouse.

In your assignment submission, you must provide the following information in a clear and organized manner:

1. Your null and alternate hypothesis stated in the context of the study

2. The mean, standard deviation, standard error, 95% CI, and sample size for the sample data (per treatment level)

3. A boxplot of the sample data

4. A residual plot

5. A normal Q-Q plot

6. A statement on whether the sample data meet each of the assumptions listed in section 1, and why you drew this conclusion

7. (And if the data meets the assumptions) The f ratio, degrees of freedom, and p value ( = 0.05) obtained by the test as part of a sentence interpreting the results of the analysis

8. (And if there is a significant result) An appropriate plot with an informative figure caption that you would include if writing a results section for the study
