    Thank you so much. The teacher for statistics we should've gotten got sick at the start of the year. So we got another teacher, but unfortunately he understood everything, but wasn't able to explain it to us, litteraly everyone of our class didn't understand what he was talking about. And with these episodes I still maneged to get a 17/20

      I dont mean to be so offtopic but does anyone know a method to log back into an instagram account?
      I stupidly lost the login password. I love any assistance you can offer me.

    Had to re-watch this video atleast 9 times, to get it down my brain but holy crap, was it worth it.
    Thanks.

    if the standard deviation is 1 shouldnt d be a subset of a??

    isnt the standard deviation in data from 1 to 0.1? making it the third largest

  • @rogersyversen3633

    the standard deviation is one? how is that easy? what is the interval that you place it in?

  • @shameer304

    1. what is the probability that a standard normal variate Z will be(a) greater than 1.09; (b) less than -1.65 (c) lying between -1.00 and 1.96; (d) lying between 1.25 and 2.75? please give solution

    It's kind of hard when numbers aren't whole numbers. My mean came out to 2.92 so it's very hard for me to graph it :( But I can kind of understand how to do this better. My professor barely went over this so I'm pretty confused. This helps a lot :)

    I feel like a>d, If question d is interpreted as the area 1 sd from the mean, which is 34%.

      that makes sense, but khan says so 😂

    If the standard deviation is 1, then shouldn't it be equal to 68%? making it second largest?
