1. Finish your chapter 22 reading quiz! This is your first quiz grade of the 4th quarter, so get it done! If you don't have the paper, look at yesterday's blog post for the questions.
2. If you haven't turned in your stamps, tomorrow is your last chance to bring them in!
3. Please use the context below and do each of the following:
- The Context:
-
Who’s more intelligent, men or women? To find out what people think, Gallop polled 520 women and 506 men. Pollsters showed a list of attributes and asked participants to indicate whether it generally applied to a man or woman. 28% of men thought men were more intelligent, but only 14% of women agreed. Is there a gender gap in opinions about which sex is smarter? What would we estimate the size of this gap to be?
- Find n, p-hat, and x for each sample (men and women)
- Check the 3 conditions (10%, random sample, success/failure) for BOTH samples (men and women)
- Show the "work"--that is, substitute the appropriate values into the formula for a 2-proportion z-interval
- Calculate the 2 proportion z-interval using your graphing calculator
- If you'd like to get ahead, try to interpret your interval! That's the hard part with these...
