Question 3: Where are the mode, the lower tail and the upper tail of this distribution?
The mode is the value of the variable at highest part of the graph, the region of highest frequency. This is where arm circumference is between 240 and 260 mm.
The lower tail is the part of the distribution where there are relatively few observations and these are small. This is where the arm circumference is below 240 mm.
The upper tail is the part of the distribution where there are relatively few observations and these are large. This is where the arm circumference is above 300 mm.
