Final answer:
To find the area under the normal curve not between -0.22 and 1.79, calculate the areas to the left of z=-0.22 and to the right of z=1.79, and add them together.
Step-by-step explanation:
The student is asking to find the numerical value of the area under the normal curve that is not between -0.22 and 1.79. To do this, we need to use a standard normal probability table or software/calculator with statistical functions to find the areas to the left of z=-0.22 and to the left of z=1.79.
Once these values are obtained, we add the area to the left of z=-0.22 to the area to the right of z=1.79 (which is found by subtracting the area to the left of z=1.79 from 1) to find the total area outside this range. Let's say the area to the left of z=-0.22 is A and the area to the right of z=1.79 is B. Then, the desired area is A + B.
If the areas to the left of z=-0.22 and z=1.79 are found to be, for example, 0.4122 and 0.0366 respectively, then the area outside would be 0.4122 + (1 - 0.9634), which is 0.4122 + 0.0366, equaling 0.4488. However, since this is hypothetical you would need to replace these figures with the actual values you obtain.
