I believe that it deals with standard deviations you need to look at a graph of the standard deviation.

The 95\% confidence interval for the population mean is \left( {6.93,11.45}\right) means that there are 95\% chances of the population mean lies in the interval.

Further Explanation:

Explanation:

The formula for confidence interval can be expressed as follows,

\boxed{{\text{Confidence interval}}=\left( {\overline X  \pm ME} \right)}

ME represents the Margin of Error.

The confidence interval has two limits.

(1). Upper Limit

(2). Lower Limit

The upper limit can be calculated as follows,

{\text{Upper limit}}=\left( {X + ME}\right)

The lower limit can be calculated as follows,

{\text{Lower limit}} = \left( {X - ME}\right)

The given confidence interval is \left( {6.93,11.45}\right).

The upper limit of the confidence interval is 11.45.

The lower limit of the confidence interval is 6.93.

The 95\% confidence interval for the population mean is \left( {6.93,11.45}\right) means that there are 95\% chances of the population mean lies in the interval.
