Answer 1

The mean duration of time spent making a decision on which movie to rent at a Redbox kiosk is 187 seconds.Option C is correct.

Step-by-step explanation:

To find the mean, we add up all the values and divide by the total number of values. In this case, we have the following values for the duration of time spent making a decision on which movie to rent:

1. 800 seconds
2. 700 seconds
3. 600 seconds
4. 500 seconds
5. 400 seconds
6. 300 seconds
7. 200 seconds
8. 100 seconds
9. 0 seconds

Adding these values together, we get a total of 3800 seconds. Since there are 9 values, the mean is 3800/9 = 422.22 seconds. Therefore, the correct option is 187 seconds (C).
