n a poll, 6767% of Internet users are more careful about personal information when using a public Wi-Fi hotspot. What is the

a_sh-v [17]

Answer:

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 volunteered 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 response bias.

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

Mazyrski [523]

Answer:

c) it will always return with an answer of 7 or fewer comparisons of data.

Explanation:

As maximum number of comparison in worst case for sorted binary search is log₂n, here n = 100, so maximum search is at least 6.6 which is approximately 7.
