The sum $\sum \mathrm { x } _ { \mathrm { i } }$ means to add all the given values of $x_i$. Thus, $15 + 3 + 11 + 16 + 16 = 61$.

Solve the Problem x1=15,x2=3,x3=11,x4=16\mathrm { x } _ { 1 } = 15 , \mathrm { x } _ { 2 } = 3 , \mathrm { x } _ { 3 } = 11 , \mathrm { x } _ { 4 } = 16x1​=15,x2​=3,x3​=11,x4​=16
