Matilda has constructed three confidence intervals, all from the same random sample. The confidence levels are $95\mathrm{\%},\text{}98\mathrm{\%},\text{}99.9\mathrm{\%}$ . The confidence intervals are

$6.4<u<12.3,\text{}5.1u13.6$ and $6.8<u<11.8$ Unfortunately, Matilda has forgotten which confidence interval goes with level. Match each confidence interval with its level.

What confidence goes with each the confidence level and indicate whether these confidence intervals are for a population mean or for a population proportion, also include support with the results.
