- How to use the standard normal table with probabilities between the mean and positive z values. 8 examples shown, see description for hyperlinked table of contents.
Corrections:
1. @1:40, 'the first 2 decimals' should be 'the first 2 digits'. 'The 3rd decimal' should be 'the 3rd digit.'
2. @7:42 the area between 1.08 and 2.45 = .133.

you have a calm voice that makes me feel relaxed when listening
I know this an old video but this by far the most helpful video on this topic. This was great!
i've no word thank you for helping me out may God bless u🙏
This is more than enough for someone to understand

Thank you very much. I've been finding a video that'll help me with my homework and your video helped me out! Thanks!!!! 💖 💖 💖
Glad this has helped!
seems like you have done a mistake in the calculation of 0.4929-0.3599=0.133
You are correct, Ameerah. I will add a correction in the description. Funny, as many times as I proofread this, I missed this error. Thank you.
GOD BLESS YOU
THANK YOU SO MUCHH. now i understand how to use thiss :')

Shanika, I'm glad the video helped.
Agreed
Great video ❤️
Thank you, Abass Kabbia. I'm glad it helped. 🤓
Thank you
What if the given is -2.4 greater than or equal to P less than or equal to 2.4
Because we know the normal distribution is symmetric, and 100% of area is under the curve, find the percent of area between 0 and 2.4 and then double it, since that same area is between 0 and -2.4. Hope that's helpful!
Set the speed at 1.25x thank me later HAHAHA
The joy of being able to control play speed.
Pls answer asap.. When do we need to add. 50
Hi, Soju, it depends on what question you're trying to answer and whether you're using this particular table. For example, if you were asked to find the probability of z > -1, and you're using the table I show in the video, then the easiest way is to look up z at 1. That will give you the area between z = 0 and z = 1. Then, because z is normally distributed, this is the same as the area between -1 and 0. Add 0.5 to that answer, and you have the final answer. The way you have solved P(z > -1) is to add P(-1

I'm sorry that I'm unable to translate this to Cebuano. You could do a project in your class with your teacher to make a RUclips video for how to use the standard normal probability table.
dayumm this is the best, very concise !! thank u vv much
You're welcome! Glad it helped.
Thank you
