Please help me compute standard deviation! Here is the problem, as written.
aleksandr82 [10.1K]

Answer:

The standard deviation for the income of super shoppers is 76.12.

Step-by-step explanation:

The formula to compute the standard deviation for the grouped data probability distribution is:

\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}

Here,

<em>x</em> = midpoints

\mu=\sum x\cdot P(x)

Consider the Excel table attached below.

The mean is:

\mu=\sum x\cdot P(x)=32.3

Compute the standard deviation as follows:

\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}

   =\sqrt{259.71}\\\\=76.1155204\\\\\approx 76.12

Thus, the standard deviation for the income of super shoppers is 76.12.
