A random sample of size n = 36 is drawn from a population with a standard deviation of s = 11.3 and sample mean x= 105.2. Construct a 90% confidence interval for the population mean μ.

Because you want a 95 percent confidence interval, your z*-value is 1.96. Suppose you take a random sample of 100 fingerlings and determine that the average length is 7.5 inches; assume the population standard deviation is 2.3 inches. ... Multiply 1.96 times 2.3 divided by the square root of 100 (which is 10).
