b. We will sometimes find a significant difference by switching to an alpha level of .01 with the same sample results.
c. We will sometimes find a significant difference by switching to an alpha level of .001 with the same sample results.
d. We will always find a significant difference by switching to an 80% confidence interval with the same sample results.
a. Always
b. Sometimes
c. Sometimes
d. Always
Significant result:
(A) Significant result at 0.05 level of significance represents that p value should be less than 0.05. So, significance level is 0.10, due to this p value less than 0.05 level will always be less than 0.10 significance level.
(B) Significant result at 0.05 level of significance shows that p value should be less than 0.05. So, significance level is 0.01, due to this p value less than 0.05 level will sometimes be less than 0.01 significance level.
(C) Significant result at 0.05 level of significance shows that p value must be less than 0.05. So, significance level is 0.001, due to this p value less than 0.05 level will sometimes be less than 0.001 significance level.
(D) Significant result at 0.05 level of significance shows that p value should be less than 0.05. So, significance level is 0.20 or confidence level of 80%, due to this p value less than 0.05 level will always be less than 0.20 significance level.
