    【Question】
    Calculate the average inspections per year done by Jessica Anthony from 2010 to 2017. from 2010 to 2017 refers to inspection_date > '2010-01-01' AND T2.inspection_id < '2017-12-31'; average inspections per year = divide(count(inspection_id where inspection_date > '2010-01-01' AND T2.inspection_id < '2017-12-31'), 8)

    【Evidence】
    from 2010 to 2017 refers to inspection_date > '2010-01-01' AND T2.inspection_id < '2017-12-31'; average inspections per year = divide(count(inspection_id where inspection_date > '2010-01-01' AND T2.inspection_id < '2017-12-31'), 8)

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT CAST(COUNT(CASE WHEN T1.first_name = 'Jessica' AND T1.last_name = 'Anthony' THEN T2.inspection_id ELSE 0 END) AS REAL) / 8 FROM employee AS T1 INNER JOIN inspection AS T2 ON T1.employee_id = T2.employee_id WHERE strftime('%Y', T2.inspection_date) BETWEEN '2010' AND '2017'
