Question

For some value of Z, the value of the cumulative standardized normal distribution is 0.8340. What is the value of Z?

A. 1.06
B. 0.07
C. 0.97
D. 0.37

Answer 1

The value of Z that corresponds to a cumulative standardized normal distribution of 0.8340 is approximately 0.97.

Step-by-step explanation:

To find the value of Z that corresponds to a cumulative standardized normal distribution of 0.8340, we can use the z-score formula. The z-score formula is z = (x - mean) / standard deviation. In this case, the cumulative probability is 0.8340, which corresponds to the area to the left of the z-score. By looking up the z-score in the z-table, we can find that the value of Z is approximately 0.97. Therefore, the correct answer is C. 0.97.
