A potato chip manufacturer produces bags of potato chips that are supposed to have a net weight of 326 grams. Because the chips vary in size, it.is difficult to fill the bags to the exact weight desired. However, the bags pass inspection so long as the standard deviation of their weights is no more than 3 grams. A quality control inspector wished to test the claim that one batch of bags has a standard deviation of more than 3 grams, and thus does not pass inspection. If a sample of 28 bags of potato chips is taken and the standard deviation is found to be 3.8 grams, does this evidence, at the 0.05 level of significance, support the claim that the bags should fail inspection? Assume that the weights of the bags of potato chips are normally distributed Step 2 of 3: Compute the value of the test statistic Round your answer to three decimal places

Assume that the weights of the bags of potato chips are normally distributed Step 3 of 3: Draw a conclusion and interpret the decision Answer 2 Points Keypad Keyboard Shortcuts We reject the null hypothesis and conclude that there is insufficient evidence at a 0.05 level of significance that the bags should fail inspection We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.05 level of significance that the bags should fail inspection We reject the null hypothesis and conclude that there is sufficient evidence at a 0.05 level of significance that the bags should fail inspection o we fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.05 level of significance that the bags should fail Inspection
