Table schema:
CREATE TABLE table_name_57 (blank_ends VARCHAR, shot_pct VARCHAR, stolen_ends VARCHAR, skip VARCHAR)

Question: What is the number of blank ends when the stolen ends were 17 and Jennifer Jones was skipped with a more than 83 shot pct?
SQL: SELECT COUNT(blank_ends) FROM table_name_57 WHERE stolen_ends = 17 AND skip = "jennifer jones" AND shot_pct > 83
