Question:

x-bar = 30, n = 25, s = 4, confidence level = 90%
We have provided a sample mean, sample size, sample standard deviation, and confidence level. In each case, use the one-mean t-interval procedure to find a confidence interval for the mean of the population from which the sample was drawn.
