Final answer:
The z-value that corresponds to an area of 0.26 to its left in a standard normal distribution is -0.61.
Step-by-step explanation:
To calculate the z-value that corresponds to an area of 0.26 to its left in a standard normal distribution, we can use the z-table or a calculator with the invNorm function. Using a calculator, we can input the area of 0.26 and find the corresponding z-value of -0.61. Therefore, the z-value that corresponds to an area of 0.26 to its left is -0.61.
