Let me calculate the total donations for each of the new intervals:
1. $0-19: This combines $0-9 and $10-19
- $0-9: approximately 3 donations
- $10-19: approximately 5 donations
- Total: 3 + 5 = 8 donations
2. $20-39: This combines $20-29 and $30-39
- $20-29: approximately 9 donations (highest bar)
- $30-39: approximately 2 donations
- Total: 9 + 2 = 11 donations
3. $40-79: This combines $40-49, $50-59, $60-69, and $70-79
- $40-49: approximately 1 donation
- $50-59: approximately 3 donations
- $60-69: approximately 3 donations
- $70-79: approximately 4 donations
- Total: 1 + 3 + 3 + 4 = 11 donations
Both $20-39 and $40-79 have 11 donations each, which is more than $0-19 with 8 donations.
Wait, let me double-check my estimates to be more precise. Looking at the histogram again, I might have underestimated some bars.
Actually, let me reconsider the $40-79 range. The $70-79 bar appears to be closer to 5 than 4, and the $50-59 and $60-69 bars might be closer to 4 each rather than 3. Let me revise:
$40-79:
- $40-49: approximately 1 donation
- $50-59: approximately 4 donations
- $60-69: approximately 4 donations
- $70-79: approximately 5 donations
- Total: 1 + 4 + 4 + 5 = 14 donations
This would make $40-79 the interval with the most donations.
Based on my analysis of the histogram, here are the answers to all questions:
1. Approximately 3 people donated between $50 and $59.
2. The most people donated in the $20-29 interval (approximately 9 donations).
3. Approximately 10 people donated $50 or more to the fund (3 in $50-59, 3 in $60-69, and 4 in $70-79).
4. People are more likely to donate smaller to moderate amounts of money (around $20-29) rather than large amounts. This is evident from the histogram showing a peak at $20-29 and then decreasing as the dollar amount increases.
5. If the histogram were redrawn using the intervals $0-19, $20-39, and $40-79, the $40-79 interval would likely have the most donations (approximately 14), followed by $20-39 (approximately 11), and then $0-19 (approximately 8).
