|
probability of the results is 0.2%
|
|
|
results are significant and can be generalized
|
|
|
probability of the results being due to chance is set at 2%
|
|
|
results are not statistically significant and cannot be generalized
|
Detailed explanation-1: -P-value = 0.02 means that the probability of a type I error is 2%.
Detailed explanation-2: -As the p-value is 0.02 and less than the alpha of 0.05, the researcher rejects the null hypothesis because there is statistical significance. By rejecting the null hypothesis, the researcher accepts the alternative hypothesis.
Detailed explanation-3: -Use the 0.02 significance level: reasonable to conclude that the mean gain or loss in time for tne watches is 0. Do not reject Reject Is noc Estimate the p-value The p-value Is greater than 0.20 between 0.01 and 0.02 less than 0.001 between 0.02 and.
Detailed explanation-4: -For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. Lower significance levels indicate that you require stronger evidence before you will reject the null hypothesis.
