The printing time of a weekly magazine was studied using two different machines, and . Eight different magazines were randomly assigned to each of the two printing machines, and produced standard deviations = 2.08, and = 1.66 for machines and , respectively. Assume the required assumptions are met and use = 0.05 to determine if the variances for the two machines are different.
Test Statistic = ______________
Reject Region: Reject H0 if F > ______________
Conclusion: ______________
There is ______________ to indicate a difference in the population variances.
Standard Deviations
Measures of the amount of variation or dispersion of a set of values, indicating how spread out the values are from the mean.
Population Variances
A measure of the dispersion of a population data set, representing the average of the squared differences from the Population Mean.
Test Statistic
A value calculated from sample data during a hypothesis test, used to determine the likelihood of a hypothesis being true.
- Implement the F-test to compare variances between two populations.
- Execute tests of hypotheses concerning population variances and elucidate the findings.
