Good day When doing some of the practice questions involving using the standard normal distribution tables the tables from the "FORMULAE AND TABLES for EXAMINATIONS" give the z-score values to two decimal places and on the memo they use three to four decimal places and hence the answers are usually a bit different. Is there any other tables we are expected to use to calculate these probabilities? Best
Good morning You can use linear interpolation with the values from the Tables, or Excel or R to get more accurate probabilities. There are no other tables.
