Your the goat
Can you also subtract 25 from 34 on D
No, if you do this you would have the probability that the number of cat households is between 26 and 34 (not what we want for this one).
This is extremely helpful
THANK YOU SO MUCH. Do you know how hard i struggled with this 😭😭😭😭
I dont get what the percentages mean. Does it mean that youre least likely to run into someone that owns a cat?
According to the statistic shared at the beginning of the problem, if we choose a house at random there is a 30.4% chance that they will have a cat. The rest of the percentages are based off of a random sample of 100 households.
@professorsethd I get that part but what does the percentage mean for all the questions for example exactly 35 own a cat?
@@305dadecounty305 If we collect data from a random sample of 100 households, there are many different possible outcomes. We might find that 0 of them have cats, we might find that all 100 have cats, we might find that 50 have cats, etc. According to the statistic given at the beginning of the question, our most likely result is that 30 of them will have cats. But, even that result is not highly likely, due to the fact that there are so many possible outcomes. Using the binomial calculator, we find that the probability of us finding 35 households with cats (out of our 100 randomly selected homes) is .051, or 5.1%. For comparison purposes, our most likely result is that we find 30 households with cats. But even this outcome only has a probability of 0.086 (using the binomial calculator). Because there are so many possible outcomes for this scenario, no single outcome has a very high probability. Anyway, that's what the percentages mean here.
@professorsethd thank you very much! I feel like a lot of channels tell you how to calculate the answer but don't really explain the answers at times. Thanks for replying, seriously appreciate it.
youre awesome thank you!!
Thank you, thank you, thank you. This video finally made the concept click for me :)
Great video, man! Keep the awesome content rolling!!! 👍👍❤️❤️🎉🎉

THANK YOU!!!! I legit could not understand this nowhere else!!!
Thank you sooo much. 🤗🤗🤗
wouldn't binomialcdf be used to find 25 or less instead of "less than 25" because it's cumulative?
2:39 My calculator returned an "Error", then I found that I entered "304" rather than "0.304" for the p value. Edit: No wonder. Probability is determined by a value from 0.00 to 1.00. There is no "304 probability". ;)
how can I download this calculator?
Thank you
This has been very helpful thank you
Excellent Lecture
Thank you!
THANK YOU SO MUCH. i was so confused on how to navigate "at least" statements with the calculator but you made it so easy. thank you.
Atleast = 1-
Thank you so much you saved my life
After pressing var stats, on my TI 84 Plus Silver Edition it does not show my list and freq list. I can only choose L1, so it gives me an error. Is there a way I can make that secondary menu show up. Thank you
Maybe try adding a comma after L1, then add L2 (press 2nd, then 2). It should look like: 1-Var Stats L1, L2
@@professorsethd that worked perfectly thank you so much. And great video.
thank you this is still helpful after 8 years
Can you do for o level statistics paper 2 question because I struggle with those questions
thanks a bunch
Hey Seth. It's Blue. Remember me from Brief Calculus Fall 2021? I'm watching this video for my online stats class. Just wanted to say hello have a great day and thanks for the helpful video!
Thank you so very much! I was struggling with the last part and this helped!
Thank you very much sir
THANK YOU!! this helped me so much!!
Around the 4:47 mark, I make a typo. I entered 8 instead of 48 in L1. So, obviously, the results here are incorrect.
I made a typo in the calculator in the employee promotion example, so the test statistic and P-value are off by a little bit...the conclusion is still correct, however! The z-statistic should be 2.082 and the p-value should be 0.019
you should have sqrt +/- 3 instead of 6.
That is true...Oops.
Well done! You're at it again with Christmas mathematics. First it was calculus for the Christmas tree, now it's math with wrapping presents. I always enjoy watching these kinds of videos. Thanks Seth! Merry Christmas
Hey thanks for watching bud...hope you find it helpful!
Got to have a better mic. Can't hear you bro
Pause at 14:22, looks like he's rapping and throqing gang signs lol thank me later
Thank you for posting this, it really helped a lot
:) In my defense, the number of thicknesses of a piece of paper that would equal the height of the Arch is 1.89 million. I wasn't too far off--especially since I didn't know the exact height of the Arch. Not in my defense, that wasn't the question that you asked, so... Thanks for asking me, this was fun and I hope to do it again next year!
Great examples! Just so you know most people never will trust a man in a bow tie.
