In class students learned how to create a confidence interval for sample proportions (on calc. - 1prop-Zint). Remember, whenever you are creating a confidence interval, check the appropriate assumtions and conditions (10 RIBS..thank you Jenae). Afterwards, we can use the calculator to calculate the appropriate confidence interval. Finally, you must also interpret the interval correctly. Give we never know the p, or the true proportion, we should state for example:
" I am 95% confident that the true proportion of high students who like Taylor Swift is between 62 and 71%."
The homework is listed below and the notes are attached.
