We want to construct a 95 percent confidence interval for the population mean. Confidence Interval Estimates for the Mean: If the population standard deviation is unknown and sample size is less than 30 then we use t-distribution and the confidence interval becomes
=(60.788,69.212) Therefore, the 95 percent confidence interval for the population mean is (60.788, 69.212). hence, the final answer is : The 95% confidence interval is (60.788,69.212).
