Final answer:
The area under the standard normal distribution curve between z=0 and z=1.24 is approximately 0.3921.
Step-by-step explanation:
To find the area under the standard normal distribution curve between z = 0 and z = 1.24, we need to find the area to the left of each z-score and then subtract the two areas. Using the standard normal distribution table or a calculator, we can find that the area to the left of z = 0 is 0.5 and the area to the left of z = 1.24 is 0.8921.
Subtracting these two areas, we get 0.8921 - 0.5 = 0.3921. Therefore, the area under the standard normal distribution curve between z = 0 and z = 1.24 is approximately 0.3921.
