SOLVED: Normal Distribution & Sampling Distribution (TiNspire)

Below is a typical Normal Distribution problem that will be solved further below using the Statistics Made Easy app .

Using the Normal Distribution feature in the Statistics Made Easy app , we enter the given mean and standard deviation in the top box use 0 and 19 for A and B to 0.0324 or 3.24% .

 

For question 2 we use 90 and 130 instead in the 2. box to 85.83%

For the 3. question we use 130 as A and some large B such as 500 (or 1000) to get 0.1092 or 10.92% as the answer.

 

For Sampling Distribution we use the Central Limit Theorem

and enter the known mean, standard deviation and sample size to get the sampling distribution

N(mean, std dev/square root(n) ). Here we get 114 and 1.3

Since the sampling distribution is a normal distribution , we go to the previous and only change the standard deviation to 1.3 instead of 13. Below, we type in the given 110 and 116 to get 93.6986%

That was not too difficult at all! It was easy..

“Tinspire applications and their customer service are great”

The Tinspire applications and their customer service are great.

The demo videos are very good.  I had been an EE for a large cellular design and manufacturing company for the past 25 years.  Now that I am interviewing for other jobs, it becomes apparent that these jobs depend and require a fluency in the fundamentals.   I am just now starting this Laplace curriculum.

It is great to have these TINSPIREAPPS tools available for my current predicament and feel they should significantly contribute to my skill set and confidence as I pursue new opportunities.

Lower & Upper Inner (Outer) Fence , IQR , 5 Number Summary (Tinspire CX)

If your Stats teacher is asking you to compute things such as:

  • Lower & Upper Inner (Outer) Fence
  • IQR
  • 5 Number Summary

and you have a Tinspire CX CAS then head over to Statistics Made Easy which actually makes Statistics a lot easier: Finding Mean, Median, Mode, Standard Deviation, Variance, Fences, IQR, Statistical Tests, Distributions, Confidence Intervals and a whole lot more …

 

Bernoulli Equation using the TiNSpire CX calculator

Solving the Bernoulli Equation is pretty once you run the Physics Made Easy app using the TiNspire CX.

Go to Menu Option 6,L : Bernoulli Equation

In the next you will see the Bernoulli Equation and the boxes for the variables involved.

Just fill in all but one box , the variable you are solving for.

In this example, we solved for Pressure p1. The final answer shows at the very bottom including the solved equation.

Correlation Coefficient and Coefficient of Determination using the TiNSpire – Step by Step

Using Statistics Made Easy at https://www.tinspireapps.com/?a=SPME and menu item

Linear Regression you just type in the given x and y values. Next the linear regression is computed for you along with the  Correlation Coefficient and the Coefficient of Determination.

That simple.
