this is very helpful! the best on CZcams
You are amazing! I am taking introductory statistics online using this textbook and your videos are a life saver!
Very simple. Thank you very much.
thank you i was looking for this book!
2024 and you have helped me saved my midterm exam, thank you so much!!!
at minute 14... I don't understand how you got the values of x-mu. 3-3.7143 does NOT equal -0.1743. none of those numbers equal x-3.7143. am I losing my mind? what am I missing?
Hey, thank you for your videos! they really helped me out in my exam for statistics !!! I was easily able to understand way better than with my professor.
you are better than my teacher LMAO, thank u
You are the only one on CZcams who reads questions very clearly! Thank you
Finally I found this book's examples❤
me when the professor allows us to use scientific calculators for the exams
Thank you so much!
Why do you add 2
Great video helps a lot especially in college when you forget basic algebra Lol
My statistics class (at another CA community college) didn't have any sort of lecture or teaching. Lynn, your videos really helped me more than you can imagine. My A in statistics is due in no small part to you. Thank you for posting your videos to CZcams. You're a terrific teacher, even for people that aren't in your classes!🙂
Thank you Michael for your kind words. I'm thrilled I could help you through your Statistics journey. AMAZING grade!! As I tell my students who earn "A" -- it wasn't me. You put in the hard work and EARNED it! Congratulations!!! 🎉🎉
Awesome explination! Super helpful! Thank you!
I'm so glad it helped 😀
On average ,how long would five computer parts last if they were used one after another? was not answered... question #2
On average one computer part will last 10 years and if we use one right after the other... 5 parts * the average of 10 years = 5 * 10 = 50 years (this is an average amount of time 5 parts used one after the other will last).
3:49 sorry, but where does it say the incredibly small amount 0.000001? Where does it show that #?

I keep getting error 8c010001
If 'poissoncdf(147,160)' includes values up to and including 160, then wouldn't the '1 - poissoncdf(147,200)' exclude 200 from the calculation? Which would make the results actually be for greater than or equal to 201?
Hey Robert, Yes! If you want x ≥ 201 and have the average of 147 then you can use the TI-84+ to calculate 1 - poissoncdf(147, 200). Using this function will take 100% of possible outcomes (aka =1 for probability) and "cut off" the cumulative probabilities for 0 to 200 leaving you 201 and more.
OMG this video is a life saver, not to mention time saver!! THank you so much!!!
You are very welcome. I'm glad it helped
That was great!
Without you I'd be lost in my upcomming exams. Thanks for the easy explanation.
Thank you!! you are smart
Thank you for the compliment.
I have this exact book. Essentials of Basic Mathmetics by Charles P. Mckeague. thats Chapter 3/ 3.5 even though you copied all of what they did in every example its still helpful seeing it written out. im taking a class in college so this is how i know the book and the exact examples given.
Ma’am, I would like to thank you, you teach these topics so well and have literally saved me this semester of college. Best wishes,
Ive found myself visiting your video out of all the other tutorials, very easy to understand and the videos are fairly short
Love your straight and to the point.
Absolutely wonderful! Clean and concise. And the 'trick' for solving the probability for an interval between two values was golden.
Question when the trial ends does it automatically charge me?
Thank you so much I honestly struggle at math but this calculator I need for the class it will help me
Thank you so much! :)
Thank you!!!!!!!! This help tremendously.
I'm glad it helped. :-)
Thankss🤗
I look forward to more videos.Keep it up! Would you like to be CZcams friends? :)
Thank you this was perfect!!
Very straightforward and helpful
Thank you, this was very helpful!
Thank you!!!
Nice, but I can do way more on my TI Inspire CAS CX. Can solve any Stats question, and can show the graph, plus show all the steps. Thanks GOD for programmable calculators.
I know I'm not in your class but THANK YOU SOOO MUCH!!!! This helped me so much and it cleared up my confusion!
very very easy way ... thank you so much ,, i never got this from my teacher but i got it the way you teach ... well done
Thanks
Thank you so much for this indepth and extremely helpful and informative instruction on Paired Data and Graphing Ordered Pairs...this was precisely what I needed to help me with my college pre algebra math course that I am taking as a 5 unit summer session...the class is rather concentrated and accelerated due to time constraints so the material has to be learned rapidly and accurately...there is very little room for instruction during class time so having these segments and persons like yourself offer expertise has enabled me to keep pace with the material and gain a much broader understanding of the principles so as to do extremely well on homework and tests. Thank you so much and best wishes to you. Ervin L. Butler.....Sacramento, CA Cosumnes River College....Physics Major 916 968 3576
Thanks☺
You video helped my hisband.. but the audio is really bad.
Very well explained.
I was working an algebraic operation and came across 3|4-5|(9+7)= these two lines drove me nuts! Are they not brackets?
These are not brackets. In math | | means absolute value Order of operations for this problem would be: Parentheses: (9+7) = 16 3|4-5|(16) Absolute value: |4-5| = |-1| = 1 (absolute value = distance from zero) 3(1)(16) Multiplication: 3(1)(16) = 48
terrible audio
