Use the image to answer the question.
A bar chart is titled: Number of Social Media Posts Yesterday. The ranges are on x-axis and numbers on the y-axis. The data are as follows: Range of 0 to 1 shows 4, range of 2 to 3 shows 3, range of 4 to 5 shows 1, and range of 6 to 7 shows 5.
Levi makes this histogram to show the number of social media posts his friends made yesterday. How many observations are represented in Levi’s dataset?(1 point)
To determine the number of observations represented in Levi's dataset, we need to add up the number of posts for each range shown in the bar chart.
Looking at the data provided:
- The range of 0 to 1 shows 4 posts.
- The range of 2 to 3 shows 3 posts.
- The range of 4 to 5 shows 1 post.
- The range of 6 to 7 shows 5 posts.
Adding these observations together, we get:
4 + 3 + 1 + 5 = 13
Therefore, Levi's dataset represents 13 observations.
