Hypothesis

Claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 664 randomly selected adults showed that 0.2​% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly​ high, then state a conclusion about the original claim.

The results are significantly low, so there is sufficient evidence to support the claim that most adults would not erase all of their personal information online if they could.
