Confidence Intervals for Proportions
In the Module Overview, you’ll have noticed the textbook assignment for this module.
ideos are optional, and are there for your reference. Watch the video if you so choose, then complete the practice problems from your textbook.
You’ll notice, I’ve only assigned odd-numbered exercises. This is because I want you to be able to check your work as you go along. Please use good judgment and academic integrity when you complete the assignments; don’t merely copy or paraphrase the answers–that will earn you a 0–but use them to guide your answers. I recommend you complete the assignment, then check the answers, and then make corrections in a different colored pen/cil or font. This way you really have the opportunity to learn to nuances–and there are nuances–in each problem. Please
make sure to show all your work, step by step, if applicable.
If you have any questions, especially concerning my definition of copying or paraphrasing, please feel free to email me.
Feel free to do the problems by hand and then scan them to upload. I really like Genius Scan. You can also take a picture of your work instead, but I ask you make sure everything is legible before you upload the picture. You may feel more comfortable typing your answers, which is fine; just be sure that ALL STATISTICAL DISPLAYS are included (no matter the format you choose).
