Question

A researcher claims that the population variance of exam scores is greater than 1616. A sample of n=12n=12 students yields a sample variance of s2=$$24s^2=24. $$Test the claim at the 0.100.10 significance level, assuming normality. What is the correct conclusion?

Accepted Answer

There is no sufficient evidence at α=0.1\alpha=0.1 to support the claim that 16"\u003eσ2\u003e16\$$sigma^2$$\u003e16

Answer

There is sufficient evidence at α=0.1\alpha=0.1 to support the claim that 16"\u003eσ2\u003e16\$$sigma^2$$\u003e16

Answer

Not enough information

A researcher claims that the population variance of exam scores is greater than 1616. A sample of n=12n=12 students yields a sample variance of s2=24s^2=24. Test the claim at the 0.100.10 significance level, assuming normality. What is the correct conclusion?

A researcher claims that the population variance of exam scores is greater than $16$ . A sample of $n equals 12$ students yields a sample variance of $s squared equals 24$ . Test the claim at the $0.10$ significance level, assuming normality. What is the correct conclusion?
