To find the total area under the standard normal curve to the left of z1 and to the right of z2, we need to calculate the areas separately and then add them together.
Using a standard normal distribution table or a calculator, we find:
1. Area to the left of z1=-1.93: 0.0262
2. Area to the right of z2=1.93: 1-0.9748=0.0252
Adding these two areas together:
0.0262 + 0.0252 = 0.0514
Therefore, the total area under the standard normal curve to the left of z1 and to the right of z2 is 0.0514.
