Unsupported. We don’t know whether any of the recipients of aid were known or strangers to the people who gave the aid. So there’s no evidence that people are more likely to aid people they know.

Unsupported. The stimulus never mentions government relief programs or whether Hollyville residents became more likely to support such programs after receiving aid.

Unsupported. We don’t know the relationship between aid amount received and level of publicity. Although we know about the proportion of Hollyville residents who donated, that doesn’t tell us about the amount of aid received by the people to whom Hollyville donated. In addition, we don't know whether any of the disasters had varying levels of publicity.

Strongly supported. A higher proportion of Hollyville residents donated this year compared to a few years ago after Hollyville was hit by a natural disaster (tornado) last year and received aid from others.

Unsupported. Hollyville experienced a tornado. Other towns experienced an earthquake and flooding. There’s no basis to say that a tornado is more similar to what Hollyville experienced than is an earthquake.
