Question 1112362: Calvin thinks a certain potato chip maker is putting fewer chips in their regular bags of chips. He selected a random sample of 17 bags of potato chips from a normal population and calculated a P value of 0.049 for the sample.
(a) At a 5% level of significance, is there evidence that Calvin is correct? (Yes or No):
(b) At a 10% level of significance, is there evidence that Calvin is correct? (Yes or No):
Also, please explain the relationship between the level of significance and a P value. Thank you!

You can put this solution on YOUR website! Calvin thinks a certain potato chip maker is putting fewer chips in their regular bags of chips. He selected a random sample of 17 bags of potato chips from a normal population and calculated a P value of 0.049 for the sample.
Ho: u < K (claim)
Ha: u>= K
(a) At a 5% level of significance, is there evidence that Calvin is correct? (Yes or No): Since the p-value is less than 5%, reject Ho. Calvin is wrong.
-------------------------------------
(b) At a 10% level of significance, is there evidence that Calvin is correct? (Yes or No): Since the p-value is less than 10%, reject Ho. Calvin is wrong.
---------------------
Also, please explain the relationship between the level of significance and a P value. Thank you!
If the p-value is less than the level of significance, reject Ho.
Note: If the p-value is less than alpha (for a one-tail test) that means
the test statistic IS in the reject interval. So reject Ho.
