The last part is you use the x table to convert the z score to a decimal. Then since the X is greater than , you subtract the decimal from one. The answer is the probability
@@masterzoruko9680 I'm not sure if you'll still need this since this comment is from 2 weeks ago but just in case you do, you need the z table to find the answer: www.z-table.com/
Please sir I need the answer soon! It's my Assign.. .. 2 day is left to submit it. According to a Priority management survey, adults spend an average of 10 hours a day at work and commuting. Let the daily work and commute times for all adults have a normal distribution with a mean of 10 hours and a standard deviation of 1.8 hours. What is the probability that the daily work and commute time for a randomly selected adult will be i. more than 13 hours? ii. between 9 and 11 hours?
look at z tables then where 1.6 meets 0.02 is 0.0526 also rounded to 0.053 - not sure how they got the 0.4474 etc but i am sticking to z values table for normal distribution/probability calculations. find a Standard Normal Cumulative Probability Table and check the answer.
but you are also correct that if you look on the negative z table you will actually get the correct and final answer and if you look at the positive z table you will get the.4474 but u need to subtract it by 0.5 it will equal to 0.0526 because the questiuons state that greater than
i am trying to sketch a normal distribution graph based on a mean of 21.8k and sd of 1k with a range of 19-24k with a nominal value of 22k any advice? i have worked out the numbers but not sure how to show on a bell graph i worked out 19-21.8/2 = -2.8 and 24-21.8/2 = +2.2 i need to show 2 graphs and compare, changing the sd to 21.5 and see which one gives better results closer to 22k.
A school of 1000 pupils is divided into year groups as follows:- Year 7 8 9 10 11 12 13 No. Of pupils 200 175 150 150 125 100 100 A surveying is to be carried out and a committee representative of the school is to be formed of 40 pupils using stratified sampling. Calculate the number of pupils choose from each year. Please help me solve.
you have to do divide the number of year 7 students by 1000 then number of year 8 students by 1000 and so on for each year then multiply each of them by 40 and then they should give you the number of student selected in each year
literally why would you cut it off at the only part we need
Ikr wtf is this bullshit

I know right this ohn performed
It’s a marketing strategy to get you to buy the membership.
@@kittyrage8173 well that fail badly because now I will never watch another one of there videos again😂
literally the add that is what "whattt still searching math help? are the videos from 2006 really doing anything" played right before this cut off
why would you cut it to the final part omg
Cause you wouldn't want to watch a video with more than 7mins😄
Yeah fr fuck this channel

The probability of the standardized table at z=1.62 is 0.4474 which we will substract 1/2 or 0.5. Therefore, p(x>31)= 0.053.
How did you get the 0.4474? Plss response
PLS TEACH ME HOW TO SOLVE THE P(X
Hey, dear Don't you think the "Z" value in the table is 0.9474 if we compare 1.6 and 0.02.
@@kamiluzair4678 i also got that value, thank you for correcting
Why we subtract 0.5? Will u please explain
Cool video adding everything except the part I need, rad channel dad
The last part is you use the x table to convert the z score to a decimal. Then since the X is greater than , you subtract the decimal from one. The answer is the probability
thank you🙏🏾
failing stats bc of this
I wish sir could give us full vedio since most of your vedio are cut off in the middle of session .
what a cliffhanger! i got .0526
Thank you for saving everyone who got duped
How?

damn really? i got .0527.
huh my answer is .9474?
bruh why would u cut it off at the end...
You didn't watch the other tutorial that's why.
We all have shared same protest.
Truee😥😣
In calci press mod 2 time and press 1 shift and 3. And Q which is 2 and type your number ....
With this I mastered entire data science in 3 mins
Thanks for sharing
How could you cut that part at the end ?
bro i replayed this shit so many times only to realize the video just ended

He has done all just input it into a calculator
0.05262
I love your explanation but why not finish?
Thank you for your good explanation. I learn on this video. Now I already solved my modules.
「あなたの動画はとても良いですし、メッセージがた
Me watching this to calculate something for cookie clicker lmao
omfg whats the answer
It was going great till you cut out the last part i really need
Hirap pag online dimo mataga
I wish it it would be entire concept but anyway well explained
Sir if the z less than 30.how to calculate
Better than my professor
look at z tables then where 1.6 meets 0.02 is 0.0526 also rounded to 0.053 - not sure how they got the 0.4474 etc but i am sticking to z values table for normal distribution/probability calculations. find a Standard Normal Cumulative Probability Table and check the answer.
hello, it's correct 1.62 when the 1.6 meets the .02 its .4474.
but you are also correct that if you look on the negative z table you will actually get the correct and final answer and if you look at the positive z table you will get the.4474 but u need to subtract it by 0.5 it will equal to 0.0526 because the questiuons state that greater than
why is it cut???
How can you know that its is greater than or less than?
3 minutes of my life wasted on a cutted crap video
please you explain more and use less time at the solving part!!
what a waste of time. why cut it off right at the answer?
Is the answer 0.0526 coz that is what i am getting and now can't check the answer coz you left.
i.e 0.5 less 0.4474 = 0.0526
Where's part 5!! 😩
Hello Hello we need the end of the video please

2035 or 3035 which is cool but damn I feel said what if you had the perfect life and just old age caught up to you
YOU HAD TO CUT
WHY
dutty trim lad
Where is the end of the lesson?
whyd i just get edged
where's the ending?!
with a z score of 1,62 I get about .0526
same
0.0526?
How?
yes
Hey can you explain how? Plsss
Any one here please help me
Really?
Didn't even finish the problem what is this
i am trying to sketch a normal distribution graph based on a mean of 21.8k and sd of 1k with a range of 19-24k with a nominal value of 22k any advice? i have worked out the numbers but not sure how to show on a bell graph
i worked out 19-21.8/2 = -2.8 and 24-21.8/2 = +2.2 i need to show 2 graphs and compare, changing the sd to 21.5 and see which one gives better results closer to 22k.

Paano mo nakuha ang 1.62
31 subtract to 24.2 then divided it by 4.2
You did not even finish figuring the problem. So we have learned nothing lol.
wtf
LMFAO WHY DID IT CUT OFF
bruh
Are you serious right now?????😭
L video
wth
Make sure you watch the previous video
thank you for nothing
