Question

Researchers dropped 200 identical wallets on sidewalks near a large university. Each wallet contained the name and address of the owner and either a photograph of a baby, a photograph of a puppy, a photograph of a young family, a photograph of an older couple, or no photograph. The researchers hypothesized that the type of photograph left in the wallet would influence the rate of return. The wallets with a photograph of the baby and the wallets with a photograph of the puppy were left early in the morning, the wallets with a photograph of the young family were left in the afternoon, and the wallets with either no photograph or a photograph of an older couple were left in the evening. Eighty-four of the 200 wallets (42%) were eventually mailed back to the owner, as shown below.
