(N) There is only one peak in dist on data value '20' with frequency 100. - Hence it is a unimodal distribution. trit Since it is a Right skewed it is Asymmetric. clistaibutis.

Date Amount weekdays (12 Density clistas => Right skewed: til Minimum = 0 Maximum=55 data lies between internal (i) Mostof the o to 20. li Average of the data is around 20 liv) There are two peaks of the distribution one at lol & other at 20.
