5: Compute the correlation  Row 2 Column 1 STAT key: Row 3, Column 3 The Down Arrow Key The Down Arrow Key The Down Arrow Key ( D:REG) The Two Key: Row 9, Column 2 (ax+b) Second F Key: Row 4, Column 1 The One Key: Row 9, Column 1 The Comma Key: Row 6, Column 1 Second F Key: Row 4, Column 1 The Two Key: Row 9, Column 2 The Enter Key: Row 10, Columns 4 and 5


    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   Top row - first key row 2, column 1 The Down Arrow Key The Down Arrow Key (C:PROB) (nCr) lower right
2: Compute 9P5  Top row - first key row 2, column 1 The Down Arrow Key The Down Arrow Key (C:PROB) (nPr) lower right


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