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  The Menu Key: Row 1, Column 4 The Two Key: Row 7, Column 2 (STAT) The F4 key: Fourth Key in the silver row. The EXE key: Row 8, Column 5 It's blue. 
2: Enter Data  (The Menu Key: Row 1, Column 4 The Two Key: Row 7, Column 2) The One Key: Row 7, Column 1 The Five Key: Row 6, Column 2 The EXE key: Row 8, Column 5 It's blue. The One Key: Row 7, Column 1 The Six Key: Row 6, Column 3 The EXE key: Row 8, Column 5 It's blue. The Two Key: Row 7, Column 2   
 The Zero Key: Row 8, Column 1 The EXE key: Row 8, Column 5 It's blue. The Two Key: Row 7, Column 2 The One Key: Row 7, Column 1 The EXE key: Row 8, Column 5 It's blue.
3: Compute the mean  The F2 key: Second Key in the silver row. The One Key: Row 7, Column 1 (x) 
4: Compute the population standard deviation  The F2 key: Second Key in the silver row. The One Key: Row 7, Column 1 (xsn)
5: Compute the sample standard deviation   The F2 key: Second Key in the silver row. The One Key: Row 7, Column 1 (xsn-1)


    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  The Menu Key: Row 1, Column 4 The Two Key: Row 7, Column 2 (STAT) The F4 key: Fourth Key in the silver row. The EXE key: Row 8, Column 5 It's blue. 
2: Enter Data The One Key: Row 7, Column 1 The EXE key: Row 8, Column 5 It's blue. The Two Key: Row 7, Column 2 The EXE key: Row 8, Column 5 It's blue. The Three Key: Row 7, Column 3 The EXE key: Row 8, Column 5 It's blue. The Four Key: Row 6, Column 1 The EXE key: Row 8, Column 5 It's blue. Press right arrow in upper left black circle. The Two Key: Row 7, Column 2 The EXE key: Row 8, Column 5 It's blue. The Four Key: Row 6, Column 1 The EXE key: Row 8, Column 5 It's blue. The Five Key: Row 6, Column 2The EXE key: Row 8, Column 5 It's blue. The Seven Key: Row 5, Column 1 The EXE key: Row 8, Column 5 It's blue. 
3: Compute the slope of the regression line   The F2 key: Second Key in the silver row. The Three Key: Row 7, Column 3 (a)
4: Compute the y-intercept of the regression line   The F2 key: Second Key in the silver row. The Three Key: Row 7, Column 3 (b)
5: Compute the correlation   The F2 key: Second Key in the silver row. The Three Key: Row 7, Column 3 (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  The One Key: Row 7, Column 1 The Zero Key: Row 8, Column 1 The Option key: Row 1, Column 3 The F6 Key: The rightmost silver key. The F1 Key: First Key in the silver row. (PROB) The Three Key: Row 7, Column 3 (nCr) The Six Key: Row 6, Column 3 The EXE key: Row 8, Column 5 It's blue.
2: Compute 9P5 The Nine Key: Row 5, Column 3 The Option key: Row 1, Column 3 The F6 Key: The rightmost silver key. The F1 Key: First Key in the silver row. (PROB) The Two key: Row 7, Column 2 (nPr)  The Five Key: Row 6, Column 2 The EXE key: Row 8, Column 5 It's blue.


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