Answer:
The confidence interval for the true mean weight of the residents of the town can be calculated using the given mean weight and the margin of error. A common level of confidence used is 95%. The formula for the confidence interval is:
Confidence Interval = (Sample Mean) ± (Margin of Error)
Explanation:
Given:
Sample Mean = 169 pounds
Margin of Error = 5 pounds
So, the confidence interval is:
Confidence Interval = 169 ± 5
This translates to:
Confidence Interval = (164, 174)
Therefore, with a 95% confidence level, we can say that the true mean weight of the residents in the town is likely to fall within the range of 164 to 174 pounds.
