Document Summary

Let a random sample of size 17 from the normal distribution n( , 2) yield = 4. 7 and s2 = 5. 76. A random sample of size from the normal distribution yield. From the given information population standard deviation is unknown. The 90% confidence interval for single mean is as shown below: From the standard normal distribution tables, the critical value at 0. 10 level for 16 degrees of freedom is 1. 746. Therefore, the 90 percent confidence interval for is lies between.
