To find Z that puts the area equal to the confidence level “in the middle” CL specifies the area in the middle ( = 1 − CL is area “outside”, split equally between both tails. is area in one tail. OR use invnorm( , 0, 1) and take absolute value (drop the "−" sign) Without calculator: Use a standard normal probability table to find Z.

This one-sample t interval for a population mean is similar in both reasoning and computational detail to the one-sample z interval for a population proportion. The One-Sample t Interval for a Population Mean. Choose an SRS of size n from a population having unknown mean μ. A level C confidence interval for μ is: +/- t* (sx/

Use the two-sample z procedure to give a confidence interval for the difference between proportions in two populations based on independent SRSs from the populations. Use a two-proportion z test to test the hypothesis that proportions in two distinct populations are equal. Check that you can safely use these z procedures in a particular setting.

Plan: We should use a 2-sample z-interval for . The conditions were addressed in part (a). Do: The critical z for 95% confidence is 1.96, so the interval is , or . Conclude: We are 95% confident that the interval from – 0.158 to 0.018 captures the true difference in proportion of male and female voters supporting Obama in this city.
