    Thank you for your video you taught me how to calculate the 1-proportion z Test. I have been struggling for 1 hour on only 1 problem on my review. I couldn't figure it out by hand and i have the calculator for it, i wanted to learn how to solve these Test Stats by hand and with computing it in the Ti-84 calculator. I thought its best to learn both ways just in case if one way doesn't work out I always have another way to find the correct answer just in case if I were to mess up one way over the other. I could not figure it out by hand for the life of me so I decided it's time for me to learn how to solve with the Ti-84 since I can't seem to get this 1 right. You showed me how to compute the numbers I had and it was the right answer on my calculator but on my paper I had it wrong. My Stats class is online now and I have to teach myself everything and it's not easy I am spending hours and i need to hurry up to cover every chapter on my test , thanks to the Corona Virus i have to learn this way. But if I don't pass this stats class i don't pass the semester, this is my last credit to go on to a 2 year bachelor program.This video is going to help me for my test thank you sooooo much! God bless you , you saved me!

    The TI 84 plus CE came out in 2015. Why has hardly anyone made videos on how to use it? It's completely different!

    Where did the "5% significance level" come into play here? I don't see it anywhere in the equation, or being input in to the calculator

    • @OpenIntroOrg
      @OpenIntroOrg  Год назад +1

      The significance level is compared to the p-value (0.186) at about 3:50 in the video. The Greek letter "alpha" is shorthand for the significance level, so we're checking whether the p-value is bigger or smaller than than alpha. Because the p-value (0.186) is bigger than alpha (0.05), we do not reject H0.

    The problem I’m trying to solve is %’s of items in a package… not a yes or no question. Help?

    • @OpenIntroOrg
      @OpenIntroOrg  3 года назад

      Are the individual observations percentages? If that is the case, then if the individual observations are being averaged, it would be appropriate to use a 1-sample mean method.
      If that is the case, then below is a video that may be helpful:

      The video after that one in the playlist covers confidence intervals.
