Question

A senior vice president of manufacturing is seeking strong evidence to support her fear that new operating procedures have increased the percentage of overfilled drink boxes from the production line. what results would provide a strong evidence for this question?

Answer 1

If the p-value is less than the significance level, , reject the null hypothesis. (There is enough
evidence to reject the claim.)

You can use the p-value to make a statement about the strength of the evidence against H0
without using significance level,

e.g., p>.10 implies “little or no evidence against H0”,

0.05< p =< 10 implies “some evidence against H0”,

0.01 < p <= 0.05 implies “good evidence against H0”, .

001 < p .01 implies “strong evidence against H0”,

p <= .001 implies “very strong evidence against H0”
