The function should output with: matplotlib.figure.Figure: A figure object containing the histogram and PDF plot. You should write self-contained code starting with: ``` import numpy as np from scipy import stats import matplotlib.pyplot as plt def task_func(size=1000): ``` ## Instructions Your solution should be saved to: ``` /workspace/solution.py ``` The solution will be tested automatically against hidden test cases. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
