Bags of a certain brand of tortilla chips claim to have a net weight of 16 ounces. Net weights actually vary slightly from bag to bag and are Normally distributed with mean Î¼. 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 H0: Î¼ = 16, Ha: Î¼ < 16. To do this, he selects 24 bags of this brand at random and determines the net weight of each. He finds the sample mean to be = 15.68 and the sample standard deviation to be s = 0.64. Based on these data, we would reject H0 at significance level 0.10 but not at 0.05. we would reject H0 at significance level 0.05 but not at 0.025. we would reject H0 at significance level 0.025 but not at 0.01 we would reject H0 at significance level 0.01
