When the confidence level of a test is increased which of the following will happen -
Ans. is 'b' i.e., Previously insignificant values because significant o If you increases the confidence level the values which were previously out side the confidence interval will also come into that interval. o For example : ? i) If confidence level is 95% --> 95% of total sample will be distributed within confidence limits and 5% data will remain outside the confidence limit. ii) Now you have increased the confidence level to 99% 99% of data will be distributed within the confidence limits and 4% will remain outsite. So 4% more data will become significant. You can also see by formula Confidence limit = 1 - Significance level or Significance level = 1 - Confidence limit So, If confidence level increases, significance level decreases, and you know : ? "The smaller the significance level (p value), the more significant the result said to be".
No effect on significance
Previously insignificant value becomes significant
Previously significant value becomes insignificant
No change in hypothesis
