Question 265967: Create a bell shaped graph for the three solutions
a.68.26% of all such children watch between 18.24 and 30.57 hours of TV per week
b. 95.44% of all such children watch between 24.5-2*6.23 and 24.5+2*6.23 hours of TV per week
c. 99.74% of all such children watch between 24.5-3*6.23 and 24.5+3*6.23 hours of TV per week
You can put this solution on YOUR website! Create a bell shaped graph for the three solutions
a.68.26% of all such children watch between 18.24 and 30.57 hours of TV per week
Sketch a bell-shaped curve.
Select a point on the horizontal axis 1 standard deviation to the right
and another 1 standard deviation to the left of the middle of the interval
under the curve.
Mark the middle 24.5 (the average of 18.24 and 30.57)
Mark the left point 18.24; Mark the right point 30.57
-----------------------------------------------------
b. 95.44% of all such children watch between 24.5-2*6.23 and 24.5+2*6.23 hours of TV per week
Same as "a" except you pick points that are 2 standard deviations to the
right and 2 to the left. Mark the left 24.5-2*6.23 =12.04 ; Mark the right
24.5+2*6.23 = 36.96
--------------------------------
c. 99.74% of all such children watch between 24.5-3*6.23 and 24.5+3*6.23 hours of TV per week
Same as "a" and "b" except 3 to the right and 3 to the left.
