Sample size = n = 31
Sample standard deviation = s = 5.3
Test statistic is
Degrees of freedom = n - 1 = 31 - 1 = 30
Level of significance = α = 0.05
Critical value = 43.773 ( Using chi-square table)
Test statistic < critical value we fail to reject null hypothesis.
Conclusion: The population variance is 20.

Please follow the steps of hypothesis testing, including
identifying the alternative and null hypothesis, calculating the
test statistic, finding the p-value, and making a conclusions about
the null hypothesis and a final conclusion that addresses the
original claim. Use a significance level of 0.10. Is the conclusion
affected by whether the significance level is 0.10 or 0.01?
