Question 73

Multiple Choice

A test involving three brands of cell phone was conducted to compare the brands with respect to the average number of battery recharges before the battery no longer functioned properly.Six phones of each brand were tested, with the following results: Number of recharges before battery no longer functions
A test involving three brands of cell phone was conducted to compare the brands with respect to the average number of battery recharges before the battery no longer functioned properly.Six phones of each brand were tested, with the following results: Number of recharges before battery no longer functions   At a 5% significance level, test the hypothesis that the average maximum number of possible recharges prior to failure is the same for all three brands.The ANOVA table for the test is shown below.Complete the table and report your conclusion.   A) Since F<sub>stat</sub> is greater than 3.682, we cannot reject the  equal population means  null hypothesis. B) Since the p-value is greater than .05, we can reject the  equal population means  null hypothesis. C) Since F<sub>sta</sub><sub>t</sub> is greater than F<sub>c</sub>, we can reject the  equal population means  null hypothesis. D) Since the p-value is less than .05, we cannot reject the  equal population means  null hypothesis. At a 5% significance level, test the hypothesis that the average maximum number of possible recharges prior to failure is the same for all three brands.The ANOVA table for the test is shown below.Complete the table and report your conclusion.

A) Since Fstat is greater than 3.682, we cannot reject the "equal population means" null hypothesis.
B) Since the p-value is greater than .05, we can reject the "equal population means" null hypothesis.
C) Since Fstat is greater than Fc, we can reject the "equal population means" null hypothesis.
D) Since the p-value is less than .05, we cannot reject the "equal population means" null hypothesis.
