Question

Claim: Most adults erase all of their personal information online if they could. A software firm survey of randomly selected adults showed that % 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.

Answer 1

Claim: Most adults would erase all of their personal information online if they could

Sample size: 625

Yes: 50.3%

The null hypothesis, due to randomness, is p = 0.5. From the results, the claim states that p > 0.5, and the result of the survey is p = 0.503.

The result is close to the null hypothesis, so we can conclude that there is no significant evidence for the claim.

Answer:

The results are not significantly high so there is not sufficient evidence to support the claim.
