stain removal, good stain removal, and fair stain removal At a-0 025, can you conclude that the mean costs per ) lo & fandom sample of toothpastes exhibiting very good Very good GoodFair slan stain removal ounce are different? Perform a one-way ANOVA test by completing parts a through d Assume that each sample is drawn from a normal population, that the samples same variances removal removal 0 36 049 271 1.14 050 098 044 144 064 041 060 0 51 are independent of each other, and that the populations have the 0 46 0 46 (c) Calculate the test statistic (Round to three decimal places as needed) O A Since F is in the rejection region, fail to reject Ho B. Since F is not in the rejection region, reject Ho O C. Since F is not in the rejection region, fail to reject Ho D. Since F is in the rejection region, reject Ho Choose the correct interpretation below at the 2.5% significance level to I 'I the claim that the mean cost per ounce isExplanation / Answer
By using MINITAB
One-way ANOVA: response versus factor
Factor Information
Factor Levels Values
factor 3 1, 2, 3
Analysis of Variance
Source DF Adj SS Adj MS F-Value P-Value
factor 2 0.8294 0.4147 1.07 0.375
Error 12 4.6652 0.3888
Total 14 5.4946
Test statistic ,
F= 1.07
pvalue= 0.375 > alpha = 0.025
Fail to reject null hypothesis.
Since F is not in the rejection region .Fail to reject H0.
There is no enough evidence at the 2.5% significance level to reject the claim that the mean cost per ounce is same.
