### Understanding Confidence Intervals: Street Width Measurement A town mayor believes the average street is 14 feet wide. To test this, 9 streets are measured and the numbers are recorded as follows: ``` 11 10 9 14 11 12 10 13 14 ``` #### Task: Confidence Interval Calculation Your task is to find each 2-decimal answer for a 93% confidence interval. - **Small # on the interval:** - Enter the lower bound of the 93% confidence interval. - **Large # on the interval:** - Enter the upper bound of the 93% confidence interval. - **Margin of error:** - Calculate the margin of error for the interval. This exercise will help you understand how to calculate confidence intervals, which are used in statistical analysis to estimate the range of values that is likely to contain the true population parameter.
