Can you tell me the highest Ofsted number that has the Type of infants, and the Intake larger than 60?
CREATE TABLE "central_watford_west_watford_and_oxhey" (
  "name" text,
  "faith" text,
  "type" text,
  "intake" real,
  "dcsf_number" real,
  "ofsted_number" real
);
SELECT MAX("ofsted_number") FROM "central_watford_west_watford_and_oxhey" WHERE "type"='infants' AND "intake">60;
