Q$2.$ The following molarities were calculated from replicate standardization of asolution:$0\mathrm{.}5026,0\mathrm{.}5029,0\mathrm{.}5023,0\mathrm{.}5031,0\mathrm{.}5025,0\mathrm{.}5032,0\mathrm{.}5027,$ and $0\mathrm{.}5026$ M$.$Assuming no determinate $($systematic$)$ errors, within what range are you $95\%$ certainthat the true mean value of the molarity falls?How to use the following Table $4-2$ to extract $t-$Table values for given set of data at a certain confidence level?

Extract the $t-$value by looking across the appropriate Row of #$DF$ and down the Column for the required $\%$ Confidence level. What is $)=(0?$
