From a random sample of 19 bags of potato chips she calculated a P value of 0.051 for the sample. (a) At a 5% level of significance, is there evidence that Jen is correct? (Type: Yes or No): (b) At a 10% level of significance, is there evidence that she is correct? (Type: Yes or No): (c) In a statistical test of hypotheses, we say that the data are statistically significant at level a if A. a = 0.05. B. the P-value is less than a. C. a is small. D. the P-value is larger than a. Note: You can earn partial credit on this problem. preview

Answer 1

solution:

if p value is less than alpha then reject the null hypothesis there we have suffiecnt evidence toconclude

given

p value=0.051

a) here pvalue is greater than 0.05 so fail to reject H0(NO)

b) here p value is less than 0.10 so reject H0(yes)

c)the p value is less than  α(option b is correct)
