It states that approximately 12.6% of numbers will have their first digit as the number two. The auditor will investigate further if the proportion of records with a first digit of 2 is among the highest 0.5%. Find the sample proportion above which further investigation is needed if a random sample of 529 records is selected. Express your answer as a percentage, giving it correct to two decimal places.
