Answer:
1. χ² = 18.548
2. χ² = 23.685
Step-by-step explanation:
1. Confidence level is 99% (α = 0.01), but we're only interested in the left half, so α/2 = 0.005. Degrees of freedom are 7−1 = 6. Looking up in a chi square table, χ² = 18.548.
2. Confidence level is 90% (α = 0.10), but we're only interested in the right half, so α/2 = 0.05. Degrees of freedom are 15−1 = 14. Looking up in a chi square table, χ² = 23.685.
