1. Find the chi square value x 2 L corresponding to a sample size of 7 and a confidence level of 99%

2. Find the critical value x 2 R corresponding to a sample size of 15 and a confidence level of 90%

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.
