In statistical process control, if you have a sample size of $5$ and the range for the last sample is found to be $2\mathrm{.}5,$ and you want to calculate the Lower Control Limit $($LCL$)$ for the Range $($R$)$ chart, what would be the LCL for this sample?$0\mathrm{.}50\mathrm{.}70\mathrm{.}91\mathrm{.}1$
