Is there a relationship between confidence intervals and two-tailed hypothesis tests? Let c be the level of confidence used to construct a confidence interval from sample data. Let α be the level of significance for a two-tailed hypothesis test. The following statement applies to hypothesis tests of the mean. For a two-tailed hypothesis test with level of significance α and null hypothesis H0: μ = k, we reject H0 whenever k falls outside the c = 1 –  α confidence interval...

Jessica runs a mile in 7 minutes, on average, with a standard deviation of 0.3. She decided to see if using new shoes improves her time. She used the new shoes for 14 runs. For those 14 runs, Jessica got an average of 6.9 minutes. She wants to know if the new shoes helped her run a faster mile.
