Answer:
And using the property of symmetry for the confidence interval we can estimate the sample proportion with this formula:
The final answer for this case would be:
So approximately 15% of teenagers have a sibling.
Step-by-step explanation:
For this case we assume that the proportion of interest is who represent the number of teenagers who have a sibling and in order to estimate this proportion we can conduct a confidence interval.
The confidence interval for the mean is given by the following formula:
And for this case the confidence interval is given by:
And using the property of symmetry for the confidence interval we can estimate the sample proportion with this formula:
The final answer for this case would be:
So approximately 15% of teenagers have a sibling.
