CREATE TABLE table_42762 ("Element" TEXT, "Nuclide" TEXT, "Z  (  p  ) " FLOAT, "N  (  n  ) " FLOAT, "isotopic mass  (  u  ) " TEXT)

What is the highest Z (p) when the N (n) is less than 30, and scandium is the element?
SELECT AVG("Z ( p )") FROM table_42762 WHERE "N ( n )" < '30' AND "Element" = 'scandium'
SELECT AVG("Z ( p )") FROM "table_42762" WHERE "Element" = 'scandium' AND "N ( n )" < '30'
