Use a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative are If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-scor halfway between the corresponding z-scores. If convenient, use technology to find the z-score. 0.05 Click to view page 1 of the table. Click to view page 2 of the table. The cumulative area corresponds to the z-score of. (Round to three decimal places as needed.)

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.
