Answer:
The mean would be $322,343 and the median would be $196,723.
Step-by-step explanation:
Since the distribution of individual incomes is skewed to the right, it means that the distribution has a long right tail.
Drawing a distribution with this characteristic, we can see how the majority of the data falls into the left side of the graphic, meaning that a lot of people receive less income. Following this reasoning, the mean which is the amount of the data (in this case individual income) divided by the amount of people, would be the higher number, meaning that the few people who earn more money would influence in making this number higher.
Following this reasoning, the median (which is not influenced by this difference) would be the less high number.

The answer is below
Step-by-step explanation:
The standard deviation formula is as follows:
where sum means "sum of", x is a value of a data set, m is the mean of the data set, and N is the number of data.
The standard deviation formula may seem confusing, but it will make sense after we break it down. In subsequent sections we will explain an interactive example, step by step. Here's a quick preview of the steps we're about to follow:
Step 1: Calculate the mean with the data from the graph.
Step 2: Calculate the square of the subtraction between the mean and each data (that is, each x).
Step 3: add the values that resulted from step 2.
Step 4: divide by the number of data.
Step 5: take out the square root.
And in this way you can obtain the standard deviation
