# The shrimps dataset

A dataset on PCBs (Polychlorinated biphenyls) accumulation
in the adipose tissue of shrimps.

PCBs are often present in coolants, and are know to accumulate
easily in the adipose tissue of shrimps. In this experiment, two
groups of 18 samples (each 100 grams) of shrimps each were cultivated 
in different conditions, one control condition and one condition 
where the medium was poluted with PCBs.

# Goal

The research question is; is there an effect of the 
growth condition on the PCB concentration in the adipose 
tissue of shrimps. Note that the PCB concentrations were 
measured in pg/g adipose tissue.

# Develop a Rmarkdown file that weaves data analyses, plots and results and answers to the following questions.

1. Explore the data what do you observe?

2. How will you model the data? 

3. Translate the research question in a null and alternative hypothesis

4. Which test will you use to assess the research hypothesis? 

5. Formulate the assumptions of the test and assess the assumptions using diagnostic plots. 

6. If all assumptions to perform the test, complete the analysis and formulate a proper conclusion.
