Multisigma Corp. has a process they believe is operating near a six$-$sigma level and want to verify this. If the specification for a critical part in the process is $2\mathrm{.}80$ cm $`0\mathrm{.}10$ and the standard devia$-$ tion for the process is $0\mathrm{.}0169,$ at what sigma level is this process operating?

I need step by step directions on how to solve this problem in Excel $.$ please be detailed
