Suppose we have a sample of size n from a population with known standard deviation o. We build a (1-a)% confidence interval for . How would this interval chance under the following circumstances? Explain how or why the change would take place. • We collect more data (n increases), but everything else stays the same. • We increase the significance level o, but everything else stays the same. • The population standard deviation o were larger, but everything else stays the same. • The population mean were larger, but everything else stays the same.
