Question

A dot plot is titled Number of States Visited. The number line ranges from 2 to 9 in increments of 1.
Estimate the mean of the data in the dot plot.

The mean number of states visited is 2.
The mean number of states visited is 2.

The mean number of states visited is 5.

Answer 1

To estimate the mean number of states visited from a dot plot, you would typically need to count the number of occurrences (dots) for each number on the line and then calculate the mean based on those counts. Since you mentioned a range from 2 to 9 but did not provide the actual counts or display of the dots in the plot, I can't compute an exact mean.

However, here’s how you would calculate the mean if you had the counts:

1. Multiply each number (2 to 9) by the count of dots at that number to get the total sum of states visited.
2. Add all these products together to get the total number of states visited.
3. Divide this total by the total number of dots to find the mean.

Since you provided multiple-choice answers (4, 6, 2, 5) and I don't have the actual dot plot to work from, you will need to determine the counts and perform the calculation.

If you have those counts or the dot plot, please share them, and I can assist you with the calculation!
