Select all statements that are correct. The law of large numbers and central limit theorem (taken together) imply that:

The law of large numbers describes the result of performing the same experiment a large number of times. Let be examples i.i.d. drawn from a distribution . Let  be a function. Then which equation reflects the law of large numbers. A. lim 𝑛 → ∞ ∑ 𝑖 = 1 𝑛 𝑓 ( 𝑥 𝑖 ) = 𝐸 𝑋 ∼ 𝐷 [ 𝑓 ( 𝑋 ) ] . B. lim 𝑛 → ∞ 1 𝑛 ∑ 𝑖 = 1 𝑛 𝑓 ( 𝑥 𝑖 ) = 𝐸 𝑋 ∼ 𝐷 [ 𝑓 ( 𝑋 ) ] . C. lim 𝑛 → ∞ ∑ 𝑖 = 1 𝑛 𝑓 ( 𝑥 𝑖 ) = 𝑓 ( 𝐸 𝑋 ∼ 𝐷 [ 𝑋 ] ) . D. lim 𝑛 → ∞ 1 𝑛 ∑ 𝑖 = 1 𝑛 𝑓 ( 𝑥 𝑖 ) = 𝑓 ( 𝐸 𝑋 ∼ 𝐷 [ 𝑋 ] ) . E. None of the above equations is true.
