Which statement is NOT true about confidence intervals? A) A confidence interval is an interval of values computed from sample data that is likely to include the true population value B) An approximate formula for a 95% confidence interval is sample estimate ± margin of error. C) A confidence interval between 20% and 40% means that the population proportion lies between 20% and 40% D) A 99% confidence interval procedure has a higher probability of producing...

It is generally believed that nearsightedness affects about 15% of children. A school district gives vision tests to 111 incoming kindergarten children. In our sample of 111 students, we find 13% of the students were nearsighted. Construct a 90% confidence interval for the number of nearsighted kindergarteners we would expect to see based on our sample. Does this support or refute the estimate of 15%? Assume conditions are met (so don't check them)! Now that you have your interval, we...
