An Experimenter Is Concerned That Variability of Responses Using Two

question 204

Short Answer

An experimenter is concerned that variability of responses using two different experimental procedures may not be the same. He randomly selects two samples of 16 and 14 responses from two normal populations and gets the statistics: s₁² = 55, and s₁² = 118, respectively. Do the sample variances provide enough evidence at the 10% significance level to infer that the two population variances differ?
Test statistic = ______________
Critical Value(s) = ______________
Conclusion: ______________
Interpretation: __________________________________________
Estimate with 90% confidence the ratio of the two population variances.
______________
