Math Problem Statement
Solution
To calculate the proportion of mathematics test scores that are greater than or equal to 600:
-
Identify the relevant bars on the histogram:
- For scores greater than or equal to 600, we include the relative frequencies for:
- 600–650:
- 650–700:
- 700–750:
- 750–800:
- For scores greater than or equal to 600, we include the relative frequencies for:
-
Sum these relative frequencies:
Thus, the proportion of test scores greater than or equal to 600 is 0.86.
Would you like further clarification or assistance with related concepts? Here are some questions to explore:
- How is a histogram's relative frequency calculated?
- What is the difference between relative and cumulative frequencies?
- How can you calculate proportions for different intervals?
- How do histograms differ from other graph types, like bar charts?
- Can the data from this histogram be used to calculate probabilities?
Tip: When analyzing histograms, always verify that the relative frequencies add up to 1 to ensure accuracy.
