To analyze the dot plot provided, let's break down the information based on the number of "x's" representing the hours spent playing video games:
- 2 hours: 4 x's → means 4 friends spent 2 hours playing video games
- 3 hours: 3 x's → means 3 friends spent 3 hours playing video games
- 4 hours: 5 x's → means 5 friends spent 4 hours playing video games
- 5 hours: 3 x's → means 3 friends spent 5 hours playing video games
Now, we can summarize the total number of observations (friends):
- 4 (for 2 hours) + 3 (for 3 hours) + 5 (for 4 hours) + 3 (for 5 hours) = 15 friends
Now let's analyze each statement given:
-
The first day of the weekend, Nakeysha’s friends spent 4 hours playing video games. - This statement cannot be verified as the dot plot does not specify which day is which hour amount.
-
Four of Nakeysha’s friends are observed. - This statement is false as we calculated there are 15 friends observed.
-
Five total hours were spent playing video games. - This statement does not represent the total hours. It only shows the hours spent individually by various friends.
-
There are 15 observations made. - This statement is true as we calculated and confirmed that the total number of observations (friends) is indeed 15.
Thus, the true statement based on the dot plot is:
There are 15 observations made.
