Using the same sample, a two-tailed hypothesis test with significance level α will . Confidence Intervals on . and. An interval estimator is a formula that tells us how to use sample data to calculate an interval that estimates a population parameter.. The confidence coefficient is the probability that an interval estimator encloses the population parameter.. Day 19. A new example, with less information:. Now I want to know about the average height of three year old apple trees. A random sample of 60 trees gave us a standard deviation of 2.8 inches (so we’ll assume . (b) . The 95% confidence interval is 0.56 to 0.62. We are 95% confident that the interval from 0.52 to 0.62 captures the true proportion of those who would like to lose weight. . (c) . If we were to repeat the sampling procedure many times, about 95% of the confidence intervals computed would contain the true proportion of those who would like to lose weight.. for . a population proportion..
