Knowing that a z-score gives you an idea of how far from the mean a data point is,more specifically that it's a measure of how many standard deviations below orabove the population mean a raw score is. Then what z-score value separates thehighest 70% of the scores in a normal distribution from the lowest 30%?

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
