The area under the standard normal curve between -1.22 and +1.22 can be found using a standard normal distribution table or a calculator with a normal distribution function.

Here are the steps:

1. Look up the z-score in the standard normal distribution table. The value you find is the area to the left of the z-score.

2. For a z-score of 1.22, the area to the left is approximately 0.8888. This means that about 88.88% of the data falls to the left of 1.22.

3. Since the normal distribution is symmetrical, the area to the left of -1.22 is also 0.8888.

4. However, we want the area between -1.22 and +1.22. To find this, we subtract the area to the left of -1.22 from the area to the left of +1.22.

5. Since both these areas are the same (0.8888), the area between -1.22 and +1.22 is 0.8888 - (1 - 0.8888) = 0.7776.

So, the closest answer to the options given is 0.7775.
