We can conclude that the process variances are significantly different.Reject Ho. We cannot conclude that the process variances are significantly different.Do not reject Ho. We cannot conclude that the process variances are significantly different.Which machine, if either, provides the greater opportunity for quality improvements?Machine 1 offers the best opportunity for process quality improvements.Machine 2 offers the best opportunity for process quality improvements.Neither machine offers an opportunity for process quality improvements.OOO The variance in a production process is an important measure of the quality of the process. A large variance often signals an opportunity for improvement in the processby finding ways to reduce the process variance.

Solve the problem. When performing a hypothesis test for the ratio of two population variances, the upper critical F value is denoted FR. The lower critical F value, FL, can be found as follows: interchange the degrees of freedom, and then take the reciprocal of the resulting F value found in table A-5. FR can be denoted Fa/2 and FL can be denoted F1-a/2 - Find the critical values FL and FR for a two-tailed hypothesis test based on the following values: n₁ = 4, n₂ = 8, a = 0.05 0.1703, 5.8898 0.1112, 5.0453 0.0684. 5.8898 O 0.1211, 4.3541
Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. Net weights actually vary slightly from bag to bag. Assume net weights are Normally distributed. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and so intends to test the hypotheses Ho: µ= 14 versus Ha: µ<14. To do this, he selects 16 bags of tortilla chips of this brand at random and determines the net weight of each. He finds a sample mean of 13.88 ounces with a standard deviation of s test statistic? 0.24 ounces. What is the value of the A) t=-0.50 В) t%3D-2.00 C) t=-8.00 D) t=-8.33
