1.Shape :
Both the boxplots with DFL and without DFL are left skewed because the median is towards the larger values.
I.e. Both are similar in skewness
2. Spread and location:
The boxplot for Without DFT ( i.e. health = 0 ) has larger values for HTL, it is spread from 55 to 70 HTL.
and the boxplot for with DFT ( i.e. health = 1) is spread from values less than 55 to 65.
3. The boxplot for Without DFT ( i.e. health = 0 ) has median around 64 and the boxplot for with DFT ( i.e. health = 1) has median around 60

The diagram above is data of current Tasmanian devils HTL
length.
2. Let u be the population mean of Tasmanian devil head-to-tail lengths (in centimetres) in all of Tasmania now (2020). The research team decides to compare the current Tasmanian devil head-to-tail lengths mean with the mean from 20 years ago. The known mean Tasmanian devil head-to-tail lengths from 20 years ago is 65 cm. (a) Test the hypothesis whether y has changed from 65 cm. You must summarize all...
