Final answer:
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.
