N experiment was conducted to test the effect of a new stain remover. Twenty stains were treated with stain remover A and stain remover B for a week, then the number of stains removed was measured. A significance test was conducted at the α = 0.10 level for the difference in the means of the number of stains removed between stain remover A and stain remover B. The test resulted in t = 1.37 and p = 0.17. If the alternative hypothesis in question is Ha: μA − μB ≠0, where μA equals the mean number of stains removed with stain remover A and μB equals the mean number of stains removed with stain remover B, what conclusion can be drawn?
