1. The first problem involves analyzing monthly accident counts for two years, 2078 and 2079. 2. We can compare the total accidents per year by summing the monthly counts. 3. For 2078, sum all months: $$15+18+20+22+16+12+10+14+15+18+16+16=192$$ 4. For 2079, sum all months: $$18+20+22+24+18+10+8+15+13+15+16+16=195$$ 5. The total accidents increased from 192 in 2078 to 195 in 2079. 6. The second problem is a contingency table showing promotions by basis and field of teaching. 7. The table totals are given, and we can verify the sums: - Teaching total: $$20+10+10=40$$ - Research total: $$10+10+15=35$$ - Other total: $$10+8+7=25$$ - Business total: $$40$$ - Science total: $$28$$ - Nursing total: $$32$$ 8. To analyze, we can calculate proportions or percentages for each category. 9. For example, percentage of promotions by Teaching in Business: $$\frac{20}{40} \times 100=50\%$$ 10. Similarly, Research in Nursing: $$\frac{15}{32} \times 100 \approx 46.88\%$$ 11. These calculations help understand the distribution of promotions across fields and bases. Final answers: - Total accidents 2078: 192 - Total accidents 2079: 195 - Promotion percentages can be calculated as shown for detailed analysis.
