Turning the calculator off
Press The Off Key: Long thin key on the upper left. Says OFF above it.

 

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 F 1 Key: above the regular keyboard (CLR) The F 1 Key: above the regular keyboard (CS1)
2: Enter Data  The One Key: Row 3, Column 11 The Five Key: Row 2, Column 12 The Sigma Plus Key: Row 1, Column 3 The One Key: Row 3, Column 11 The Six Key: Row 2, Column 13 The Sigma Plus Key: Row 1, Column 3 The Two Key: Row 3, Column 12 The Zero Key: Row 4, Column 11 The Sigma Plus Key: Row 1, Column 3 The Two Key: Row 3, Column 12 The One Key: Row 3, Column 11 The Sigma Plus Key: Row 1, Column 3
3: Compute the mean  The STAT Key: Row 3, Column 3 The F 3 Key: above the regular keyboard (MN)
4: Compute the population standard deviation  The STAT Key: Row 3, Column 3 The INVerse Key: Row 1, Column 10 The F 4 Key: above the regular keyboard (s) 
5: Compute the sample standard deviation   The STAT Key: Row 3, Column 3 The F 4 Key: above the regular keyboard (s)


    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 F 1 Key: above the regular keyboard (CLR) The F 2 Key: above the regular keyboard (CS2)
2: Enter Data   The One Key: Row 3, Column 11 The x tilde t key: Row 1, Column 4 The Two Key: Row 3, Column 12 The Sigma Plus Key: Row 1, Column 3 The Two Key: Row 3, Column 12 The x tilde t key: Row 1, Column 4 The Four Key: Row 2, Column 11 The Sigma Plus Key: Row 1, Column 3 The Three Key: Row 3, Column 13 The x tilde t key: Row 1, Column 4 The Five Key: Row 2, Column 12 The Sigma Plus Key: Row 1, Column 3 The Four Key: Row 2, Column 11 The x tilde t key: Row 1, Column 4 The Seven Key: Row 1, Column 11 The Sigma Plus Key: Row 1, Column 3
3: Compute the slope of the regression line   The STAT Key: Row 3, Column 3 The F 5 Key: above the regular keyboard (-->) The F 1 Key: above the regular keyboard (m-b)
4: Compute the y-intercept of the regression line  The STAT Key: Row 3, Column 3 The F 5 Key: above the regular keyboard (-->) The F 1 Key: above the regular keyboard (m-b) The x tilde t key: Row 1, Column 4
5: Compute the correlation   The STAT Key: Row 3, Column 3 The F 5 Key: above the regular keyboard (-->) The F 2 Key: above the regular keyboard (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 3, Column 11 The Zero Key: Row 4, Column 11 The x tilde t key: Row 1, Column 4 The Six Key: Row 2, Column 13 The Second Key: Row 2, Column 10 It's Yellow The Eight Key: Row 1, Column 12 (nCr)
2: Compute 9P5  The Nine Key: Row 1, Column 13 The x tilde t key: Row 1, Column 4 The Five Key: Row 2, Column 12 The Second Key: Row 2, Column 10 It's Yellow The Eight Key: Row 1, Column 12 (nPr)


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