Worked Out Examples

In the following examples, we list the exact key sequence used to find the answer.  We will list the keys by the main symbol on the key.  In parentheses, we will list a helpful mnemonic, e.g. we will list ex as (ex).


A: What is the mean and standard deviation of the following list of numbers?

15      16      20      21

1: Clear Memory  Row 1, Column 1 Row 2, Column 6
2: Enter the data  Row 1, Column 1 It's Yellow Row 3, Column 6 (MODE) Row 7, Column 3 Row 7, Column 1 Row 6, Column 2 Row 4, Column 6 Row 7, Column 1 Row 6, Column 3  
 Row 4, Column 6 Row 7, Column 2 Row 4, Column 6 Row 7, Column 2 Row 7, Column 1 Row 4, Column 6
3: Compute the mean  Row 4, Column 4 Row 6, Column 1 (x)
4: Compute the population standard deviation.  Row 4, Column 4 Row 6, Column 3 (sx)
5: Compute the sample standard deviation:  Row 4, Column 4 Row 6, Column 2 (sx)


    You should get a mean of 18, population standard deviation of 2.549509757 and a sample standard deviation of 2.943920289.

B: Find the linear regression line for the following table of numbers. Also, find the correlation.

x 1 2 3 4
y 2 4 5 7

1: Clear Memory  Row 1, Column 1 Row 2, Column 6
2: Enter Data  Row 1, Column 1 It's Yellow Row 3, Column 6 (MODE) Row 7, Column 3 Row 7, Column 1 Row 7, Column 1 Row 4, Column 5 (,) Row 7, Column 2 Row 4, Column 6  
 Row 7, Column 2 Row 4, Column 5 (,) Row 6, Column 1 Row 4, Column 6 Row 7, Column 3 Row 4, Column 5 (,) Row 6, Column 2 Row 4, Column 6 Row 6, Column 1  
  Row 4, Column 5 (,) Row 5, Column 1 Row 4, Column 6
3: Compute the slope of the regression line  Row 4, Column 4 Row 5, Column 5 (b)
4: Compute the y-intercept of the regression line.  Row 4, Column 4 Row 5, Column 4 (a)
5: Compute the correlation.  Row 4, Column 4 Row 6, Column 5 (r)


    You should get a slope of 1.6, a y-intercept of 0.5, and a correlation of 0.992277876.
    The regression line would be: y = 1.6x+0.5.

C: Find 10C6 and 9P5.
1: Compute 10C6  Row 7, Column 1 Row 1, Column 1 It's Yellow Row 6, Column 2 (nCr) Row 6, Column 3 Long key on the bottom right.
2: Compute 9P5  Row 5, Column 3 Row 1, Column 1 It's Yellow Row 6, Column 3 (nPr) Row 6, Column 2 Long key on the bottom right.


You should get 10C6 = 210 and 9P5= 15120.
