Question

A company claims that the variability in production time at Plant X is greater than at Plant Y. At $alpha equals 0.10$ , the sample statistics are: $s_{1}^{2} = 950, n_{1} = 10$ and $s_{2}^{2} = 800, n_{2} = 12$ . Test the claim $sigma sub 1 squared is greater than sigma sub 2 squared$ .

Accepted Answer

Do not reject $alpha equals 0.10$

Answer

Reject $alpha equals 0.10$

Answer

The test is inconclusive

Answer

Cannot be determined

A company claims that the variability in production time at Plant X is greater than at Plant Y. At α=0.10α = 0.10, the sample statistics are: s12=950, n1=10s_1^2{}=950,\text{ }n_1=10 and s22=800,n2=12s_2^2=800,n_2=12. Test the claim σ12>σ22\sigma_1^2>\sigma_2^2.
