<prompt> When the confidence level of a test is increased which of the following will happen -No effect on significancePreviously insignificant value becomes significantPreviously significant value becomes insignificantNo change in hypothesis  <response>: 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.
