The sample standard deviation of this dataset is =19.1.

The Standard deviation is a degree of the amount of variant or dispersion of a set of values. A low widespread deviation indicates that the values tend to be near the mean of the set, at the same time as a high widespread deviation indicates that the values are spread out over a much wider variety.

Sample  standard deviation S=√∑(x-\bar x)2/n-1

=√366.6667

Dmitry_Shevchenko [17]

The answer is: the person whose photograph is snapped by the candid photographer.

Capital refers to accumulation of assets that is owned by a certain individual or organization that can be used to generate more income.

Candid photographers only take picture of the environment around them naturally (without any edits or settings). This mean that the person who is being photographed is not being paid. Since that person does not generate income, it cannot be considered as a capital.
