I'm not sure, but it probably gives the error because one of the values you entered isn't valid. It's too big or too small.

If this doesn't solve the problem, please let me know.

### I keep trying to do a 2-PropZTest, I'm inputting x1 = 11541, n1 = 41, x2 = 9853, n2 = 52, >p2, and every time I hit Calculate, the calculator says Domain error.

When I go back to check what's wrong, n1 has been replaced with n1 = 0, I have no idea why the calculator is doing this; I'm on a time crunch and I need help with this as soon as possible. Thank you for reading! BTW, I'm using a TI-84 Plus CE if that is helpful. AmanStino Ultra Slim Lightweight Smart shell Stand Cover with Auto Wake...

### Stats 2 prop z test

n1 and n2 are integers. The proportions p1 and p2 must satisfy the conditions of the Hypothesis you are testing. p1 not equal to p2, p1 < p2, p1>p2. Dec 10, 2013 | Texas Instruments TI-89 Calculator

### One of my values is being replaced with zero in the stat test options, causing a domain error. How do I fix this?

After looking in the manual, I read that
It takes as input the COUNT of successes in each sample (x1 and x2) and the COUNT of observations in each sample (n1 and n2). Thus your values of x1 and x2 must be integers (whole numbers).. Besides I duplicated your example taking x1=21, n1=43, x2=18, and n2=38 and I did not get the domain error.
I was able to draw the graph also.
You might want to check your values.

### My TI 84 plus silver: whenever I push the graph button the message ERR: Syntax 1:quit 2: goto appear on screen please help

Press the Y= button.

There are several possibilities:

1) Scroll through all equations, Y1 through Y9 and Y0. Make sure they are cleared.
2) The equation you typed in is not entered correctly.
3) Make sure Plot 1, Plot 2, and Plot 3 are NOT highlighted.

### What is the equation of the pair of points (-5,-8) and (-3, -1)

The site seems to eat the plus signs I enter, so I will use PLUS to symbolize addition.

To find the equation of the straight line (
y = a*x PLUS b) that passes through two points P1(x1,y1) and P(x2,y2) , you need to use
1. the coordinates of the points to calculate the slope a (gradient) as a=(y2-y1)/(x2-x1)
2.
Replace the calculated value of a in the equation and write that one of the points ( P1(x1,y1) for example) satisfies the equation. In other words y1=a*x1 PLUS b.
Here y1 and x1 are known values, a has been calculated, and only b is still unknown. You can now use the equation
y1=a*x1 PLUS b to calculate b as
b=(y1-a*x1)

Example: Equation of the line through (1,5) and (3,6)

Calculate the slope (gradient) of the line as a=(y2-y1)/(x2-x1) where y2=6, y1=5, x2=3, and x1=1. You should get a=(6-5)/(3-1)=1/2
The equation is y=(1/2)x PLUS b, where b is not known yet.

To find b, substitute the coordinates of one of the points in the equation. Let us do it for (3,6).

The point (3,6) lies on the line, so 6=(1/2)*3 PLUS b.
Solve for b: 6 MINUS 3/2=b, or b=9/2=4.5
Equation is thus y=(x/2) PLUS 9/2 =(x PLUS 9)/2

I trust you can substitute you own values for (x1,y1, x2,y2) to duplicate the calculations above.

### Equation of line between to points

Example: Equation of the line through (1,5) and (3,6)
Calculate the slope (gradient) of the line as a=(y2-y1)/(x2-x1) where y2=6, y1=5, x2=3, and x1=1. You should get a=(6-5)/(3-1)=1/2
The equation is y=(1/2)x PLUS b, where b is not known yet.

To find b, substitute the coordinates of one of the points in the equation. Let us do it for (3,6).

The point (3,6) lies on the line, so 6=3/2 PLUS b.
Solve for b: 6 MINUS 3/2=b, or b=9/2=4.5
Equation is thus y=(x/2) PLUS 9/2 =(x PLUS 9)/2
