Dan thinks a certain potato chip maker is putting fewer chips in their regular bags of chips. From a random sample of 20 bags of potato chips he calculated a P value of 0.112 for the sample. (a) At a 5% level of significance, is there evidence that Dan is correct? (Type: Yes or No): (b) At a 10% level of significance, is there evidence that he is correct? (Type: Yes or No): (c) In a statistical test of hypotheses, we say that the data are statistically significant at level αα if A. αα is small. B. the P - value is less than αα. C. the P - value is larger than αα. D. α=0.05α=0.05.
