In a sample of 138 teenagers, 38 have never been to a live concert. Find the sample proportion for those who have never been to a live concert.
* 4%
* 28%
* 50%
* 72%
38/138 * 100 = ?
To find the sample proportion for those who have never been to a live concert, we need to divide the number of teenagers who have never been to a live concert by the total number of teenagers in the sample and then multiply by 100 to express it as a percentage.
In this case, we have 38 teenagers who have never been to a live concert out of a total sample size of 138 teenagers.
To find the sample proportion:
Proportion = (Number of teenagers who have never been to a live concert) / (Total number of teenagers in the sample)
Proportion = 38 / 138
Now, let's calculate the proportion:
Proportion ≈ 0.2754
To express it as a percentage, we multiply by 100:
Proportion (as a percentage) ≈ 0.2754 * 100 ≈ 27.54%
Therefore, the sample proportion for those who have never been to a live concert is approximately 27.54%.
Among the given options, the closest answer is 28%.
