In this video, I go over using induction for three different proofs and describe how to use induction for proofs in general.
Z-Interval and T-intervals on the calculator (Confidence Intervals for the Mean)
Переглядів 20 тис.10 років тому
In this video, I use two examples to show you how to calculate a t interval and a z interval using a TI83 or TI84 graphing calculator. This video uses the examples from the corresponding article here: www.mathbootcamps.com/confidence-intervals-mean-using-ti83-84-graphing-calculator/
Calculating Confidence Intervals for the Mean (by hand)
Переглядів 9 тис.11 років тому
In this video, we calculate two confidence intervals and discuss when it makes sense to use a t-interval vs. a z-interval. More at: www.mathbootcamps.com/calculating-confidence-intervals-for-the-mean/ .

Using x and y Intercepts to Graph Linear Equations
Переглядів 37011 років тому
One of the fastest ways to graph a linear equation is to use the x and y intercepts. In this video, I go through how this works through some examples.
Binomial Probabilities on the TI83 or TI84
Переглядів 1,4 тис.11 років тому
Binomial probabilities can be found using the functions binomcdf and binompdf on the TI83/84 calculator. In this video, I show you how to use these to find several different types of binomial probabilities through various examples. Note1: If you have a new TI84, your menu is slightly different, but you need to input the same information. Note2: This video is from a course I am teaching through ...
Using InvNorm on the TI83 or 84 Calculator
Переглядів 3,7 тис.11 років тому
InvNorm on the TI83/84 allows us to find a value or z-score when given an area under the normal curve. The only trick is that the function always wants area to the left, so we often have to find that before using the calculator. Note: This video is from a course I am teaching through my college but I share it in case others find it helpful! Any section numbers mentioned match up with the textbo...
Using Bayes Theorem through Tree Diagrams
Переглядів 12 тис.11 років тому
To find some types of conditional probabilities, we need to use Bayes theorem. This theorem has a complex formula, but it is possible to simply use a tree diagram in its place. In this video, I go through an example of how this works and show how to calculate the final answer on a TI83 or TI84 calculator. Note: This video is from a course I am teaching through my college but I share it in case ...
How to Find Conditional Probabilities and Determine if Events are Independent
Переглядів 32 тис.11 років тому
In this video, we use mock survey data to show how you can find conditional probabilities. The wording on these can be important, so we look at questions that are worded in slightly different ways. Finally, we see how conditional probability can be used to determine if two events are independent or dependent. Note: This video is from a course I am teaching through my college but I share it in c...

How to Draw a Histogram by Hand
Переглядів 103 тис.11 років тому
Using a small data set, in this video I show you how to make a frequency distribution and the corresponding histogram by hand.

    In case anyone else is having the same issue I am, I you can only simplify fractions if the denominator is 4 digits or less if the numerator is 2 digits or less. So, any fraction that would reduce to a 1-digit numerator and 4-digit denominator would result in a decimal with more than 3 places and will not reduce with this calculator. This means anything less than or equal to 1/1000 or .001 will not reduce. I tried to do 64/140608 (2-digit numerator and 6-digit denominator) and it will only show a decimal. I tried 11/11111 and had the same result. 11/1111 will reduce to 1/101. I also experimented using .333 and .3333 and found that .3333 will not translate into a fraction of 1/3 but .333 will. * Multiples of 10! If the numerator and denominator are both multiples of 10, some zeros will cancel each other out with fractions like 100/10000 or 100000/10000000 which both reduce to 1/100. This is the only exception to the rule and you should be able to easily reduce these without a calculator* I hope this made sense and helps anyone who had the same frustrations I did!

    Thankyou (8yrs later) that is extremely helpful, I was trying to put the parameters straight into the z-test{} form, this is what I discovered, at the input query field type.. z-test{z>-1000 and z<3.0} will give the standard u=0, s=1 result 0.99865 (for Z<3) (ignore graph) use z-test{} not z-test() you need to use decimal 3.0 and not 3. you make lower limit z=-1000 which it interprets as - inf for all practical purposes. only does Left-tail so for z>-1.0 to z<3.0 you would need to do separate z-tests z-test{z>-1000 and z<3.0} then z-test{z>-1000 and z<-1.0} subtracting your answers.
