We will find the standard deviation for the data, follow the table given below.

180 17.4 302.76
192 29.4 864.36
203 40.4 1632.16
204 41.4 1713.96
189 26.4 696.96
210 47.4 2246.76
191 28.4 806.56
175 12.4 153.76
220 57.4 3294.76
211 48.4 2342.56
122 -40.6 1648.36
199 36.4 1324.96
52 -110.6 12232.36
192 29.4 864.36
122 -40.6 1648.36
82 -80.6 6496.36
104 -58.6 3433.96
181 18.4 338.56
122 -40.6 1648.36
101 -61.6 3794.56
sum 3252 0 47484.8

And standard deviation = for sample, here n=20

So, standard deviation == 49.992 (Answer)
