Saktong sakto to sir sa study guides kopo ngayon HAHAHAHA
Ang galing nagpagkaka explain, simple and brief, walang complicated and hard to understand na words and explanation. Naintndhan ko agad kht na npaka slow ko when it comes to numbers. Two thumbs up. This was really a great help for my Managerial Stats subject in MBA :) Thank youuuu!
Salamat din po at nakatulong ako. Good Luck po sa MBA niyo. God Bless you.
Galing nyo po sir..dito palang ako napacomment sa isang youtuber..thanks po
Thank you po ng marami :)
Super dali po maintindigan, Super thank you po❤
Thank you din po sa pag view :) God Bless
Sir sana po magawaan nyo din po ng video ang power with sample size
bakit po less than yung h1 (alt hypothesis) sa second problem? (0.610)?
Sa problem po raw kasi naka state in 20:04 na " test the claim of the driving instructor that his graduates had FASTER reaction times" meaning, kung mas mabilis less time. So mas mababa sa 0.610s
Good day sir pwede po ba to sa experimental research(qualitative research method?
Hi Aira Mae. It would be best if you can ask your respective teacher about it :)
I could assist you more on the topic itself like the computation. :)
paano n'yo po ikinompute yung sa 17:28 paano po nakuha yung 2.575
thankyou po sa response
Hi Suhania.
Good Morning.
I add niyo po muna iyong 2.57 at 2.58. So ang makukuha niyo na sagot ay 5.15
Ngayon, idivide niyo po siya ng 2. So--> 5.15/2 = 2.575
hello po hindi po pwede mag double yung critical value? for example po dito 10:14 dahil two tailed siya dalawang c value ang ginamit para iadd tapos iddivide so ask ko lang po if hindi pwede na dalawang 2.8
Saan niyo po nakuha iyong 2.8?
Yes two-tailed naman siya kaya dalawang +/- 2.575 na critical value
@@mathandlanguagebyjamesjuni sorry po that was suppose to be 2.58, thankyou po!!!
Thank you po sir! May I ask something? In terms po sa pag-identify if what appropriate test statistic to be used in a problem. Tama po ba ito sir? Huhu. Just want to know if my answers are right.
◾T-TEST
It has been reported that the average daily intake of calories for young women is 1667. To see if this is true for nurses, a researcher sampled 15 nurses and found their average daily intake of calories was 1593. The standard deviation of the sample was 36 calories.
◾T-TEST
For a sample of 24 operating rooms taken in a hospital, the mean level of noise was 41.6 decibels, and the standard deviation was 7.5.
◾Z-TEST
The mean of the maximum loads supported by 60 cables is 11.09 tons and the standard deviation is 0.73.
◾Z-TEST
Measurements of the diameters of a random sample of 200 ball bearings made by a machine during one week showed a mean of 0.8 inches and a standard deviation of 0.04 inches.
◾Z-TEST
A sample 50 days showed that a fast-food restaurant served an average of 182 customers during lunch (11:00 am - 2:00 pm). The standard deviation of the sample is 8.
Hoping for your response sir🥺
If you don't know the population standard deviation = Use T-test
If you know the population standard deviation and the sample size is above 30 = Use Z-test
If you know the population standard deviation and the sample size is NOT above 30 = Use t-test
@@mathandlanguagebyjamesjuni thank you so much po sir!!
Yes correct all
Papano niyo po ikinompute yung sa 13:05 pano po ang procedure na ginawa ninyo
Ty po sa response
Sa calculator, you have to use brackets like this
[(32-36)/(8/sqrt50)]
Paano po sir ma-identify if 2 tailed, left tailed, right tailed ang isang problem
Pa check po ng 03:20 :)
Hi sir! May i ask something po. Is it possible po ba na more than 4 ang vlue ng z computed value?
example po : 14.142
Dapat hanggang less than 4 lang iyon. Kindly double check na lang po iyong computation.
@@mathandlanguagebyjamesjuni
Thank you for the reply po..Here's the equation po sir :
x = 860,000
mu = 730,000
standard deviation = 65,000
n = 50
And ang answer parin po talaga ay 14.142, i tried to not include ung square root of 50..at ganito lang po :
860,000-730,000/65,000
= 2
Is it possible/valid to use po?
@@nicolai7033 Thank you for waiting; nag dinner lang me.
Regarding kanina, I stand corrected. Yes, possible naman na more than 4 ang sagot. So, ok lang kahit 14 something siya.
@@mathandlanguagebyjamesjuni okay sir, tysm po! ❤
May two sample mean po kayo?
Pasensiya po, wala pa po. Kaso soon po.
Hi po, pano nyo nakuha yung -3.54 part sa 13:06
sa numerator part --> 32-36 = -4
sa denominator part naman po --> 8/sqrt 50
-->8/ 7.071067811865...
--> 1.13137084989847603904...
numerator / denominator: -4/1.13137084989847603904...
Answer = -3.54
@@mathandlanguagebyjamesjuni Salamat po sir, grabe puyat ko kagabi hirap po talaga pag self learning.
@@jakemariannecadao9491 Ayos lang. Masaya ako na nasagot ko tanong mo :)
@@mathandlanguagebyjamesjuni thankyou po uli sir
pwd po ba sir.. humingi ng powerpoint presentation nito?
Sorry, kaso wala na kong ppt niyan. :(
