The probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.964

If the survey subjects <em>volunteered</em> to respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a <em>response bias.</em>

Explanation:

Let P(at least one is more careful about personal information when using a public Wi-Fi hotspot) denote the probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot, then we have the equation

P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot)

If 67% of Internet users are more careful about personal information when using a public Wi-Fi, then 33% of them are not.

P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot) = $0.33^{3}$ ≈ 0.036

P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - 0.036 = 0.964

A student is recording a song on her computer. When the recording is finished, she saves a copy on her computer. The student not

denis23 [38]

Answer:

A. The song was saved using fewer bits per second than the original song.

Explanation:

A song can be recorded on the computer or any device ranging from bit rates 96 kbps to 320 kbps.

The lesser the bitrates the lesser the quality of the audio and when we increase the bit rates, the quality of the audio recorded gradually increases.

Bitrates of 128 kbps give us a radio like quality whereas when we use bitrates of 320 kbps we get very good or CD-like quality.

According to the scenario, the most appropriate answer is option A.
