There is insufficient information in the question to answer it. To determine Z score, you need raw score, mean, and standard deviation. Please restate the question.
1.75
1.31
It depends on whether the interval is one sided or two sided. The critical value for a 2-sided interval is 1.75
Z = ± 1.8119 gives a two-tailed interval of 93%
The answer will depend on whether the critical region is one-tailed or two-tailed.

The value is 0.3055
coordinate, or coordinate value
The value for a one-sided confidence interval of 86% is 1.08
