From table, the best we can read is 0.83 Some tables we read 0.7673 directly and some tables read 0.2673 and we have to add 0.5 and get 0.7673, or on a more accurate TI calculator we can read 0.7976716754. We multiply by 500. So if we use the table, we get 384 bears and if we use a TI calculator we get 399 bears. Edwin
