Thank you so much 🥺, I had searched everywhere trying to understand how critical level could be found from a Z- test, I was almost giving up until I saw your video 🙌🏾 I'm grateful
Thanks a ton buddy. I was hurting my brain to find a solution that how can z 0.025=1.96 ? and now I know exactly why ... so thank you so much for making it simpler to understand. Keep teaching and keep growing good luck 🤞
Thank you very much i now know how to use the z table and how to find critical region iam beginner student also help in financial maths your explanation is so clear Prisca from Zimbabwe

Hi sir. What can we conclude from this hypothesis results using both Beta Value and Pearson Correlation? Below are the values for each variables : 1) there is a positive relationship between salary and employee retention. Beta Value : -.0379 and Pearson Correlation value : -0.289 2) there is a positive relationship between communication and employee retention. Beta Value: -0.159 and Pearson Correlation: 0.110 3) there is a no positive relationship between job satisfaction and employee retention. Beta Value: -0.115 and Pearson Correlation: -0.136
A soft drink machine is regulated so that it discharges an average of 750 milliliters per bottle. the amount of drink is normally distributed with a standard deviation of 30 milliliters. a total of 10000 bottles are filled in a day. bottles containing the lowest 10 % of the fill are sent for refilling the next day. other bottles are sent for packaging at the end of the day. what is the minimum amount of fill that guarantees the packaging of the bottles at the end of the day? can you help me this question
I'm trying how to figure out how to calculate this without a z table but I can't find an answer anywhere, I mean one person said use probability density function but idk how to do that
You need to integrate the function between the two points bounding your region. If you took Calculus, integration was covered there, but the normal function was not covered there.
A very short explanation of the meaning of confidence level and if the Za/2 correspond to such level you are obtaining from z-table could improve your explanation. Since I had to make sure of that I had to go to another video just a few seconds more explanatory for those like me who just need to refresh something learned many may gsads ago.
I fully understand. These videos are part of a large free course at my website (statsprofessor.com) The videos are organized by chapter and section. They also are accompanied by a set of course notes that explain the meaning of confidence level and the reason we need these critical values. That site and the notes/homework/sample exams are what I use to teach my university courses, so they aren't meant to appear in isolation without all of the other related materials/videos.
Hi Matthew, there are many versions of the z table. You have to look at the diagram at the top of the table to see how it works. Some tables give tail areas. Some of the tables read from the z score all the way to negative infinity, and there are at least three other versions of the table.
It depends on what the problem is asking you to find; however, any z score higher than 4.00 is going to have very little area in the tail beyond that z score. You can therefore safely assume p(z>4.00) is approximately zero. Of course, it won’t be virtually zero until you are looking for something like P(z > 7.00), but the value is likely 0 if rounded to four decimal places.

Exactly the problem that was giving me problem
Help me understand why

You’re welcome!
Your video is still savings lots including me. Thank you.
Happy to hear it!
I got so worried because i couldn't get myself to understand how i could read the table. Savior! 👍🏻

Which book is reminded for table of z test
Can you please share the table picture. I'm unable to find it anywhere. Or you just tell me how I search for this table.. kindly response it .
Tnx it helped
Great!
Is this for a two tail or a different video is made for it? Thanks anyway :D

How to find the z alpha? so not z 1/2 alpha
Saved me
Super
Thank you
Wat is in Zc using a/2?
And thanks anyway. I am sure it helps others.
Why does it in my table 0.475 come up as -0.06?
Hi Matthew, there are many versions of the z table. You have to look at the diagram at the top of the table to see how it works. Some tables give tail areas. Some of the tables read from the z score all the way to negative infinity, and there are at least three other versions of the table.
I'm ok now
Thanks for the video! I am working now on an assignment and got a z-score higher than 4, what should I do?
It depends on what the problem is asking you to find; however, any z score higher than 4.00 is going to have very little area in the tail beyond that z score. You can therefore safely assume p(z>4.00) is approximately zero. Of course, it won’t be virtually zero until you are looking for something like P(z > 7.00), but the value is likely 0 if rounded to four decimal places.
@@dmcguckian I appreciate your reply. the problem is asking me to find p(r
yeah but how do you do it using a t table
Check out the videos in section 8.2: www.statsprofessor.com/chapters.php?id=3#ptop
if it was one tailed test then how to find
Here is a video for a one-tailed test: www.statsprofessor.com/video.php?chapterId=3&id=160
Can you provide us the source of Z table used in the video
It can be found here at my website www.statsprofessor.com/pdf/Zscore.pdf
Why my z-table is different...
There are several z tables. At the top of the table(s), it will have a diagram showing how your table works.
I can't find the chart on that site for the life of me.
Hi Lucy, at STATSprof it’s located under course documents, first link in the left navigation panel: www.statsprofessor.com/video.php?chapterId=20&id=837

are you sure 0.95/2=0.4750 ?
the answer i got is 0.475
@@waleedmonim2372 it's the same thing. Because the zero is after it has no significance
