Answer 1

Arranging them in ascending order

$\\ 0.03,0.04,0.06,0.11,0.17,0.29,0.43,0.47,0.52,0.55,0.71,0.86,0.88,0.93,0.99,\\\ 1.02,1.08,1.09,1.15,1.17,1.19,1.21,1.23,1.24,1.31,1.49,1.53,1.66,1.73,1.84,\\1.91, 1.91,1.95,1.95,1.98,2.05,2.17,2.25,2.27,2.29,2.35,2.44,2.51,2.57,2.57,\\ 2.61,2.62,2.64,2.94,2.96\\\\\\ \\ Mean =\frac{\sum a_i}{n}=\frac{\left ( 73.92\right )}{50}=1.4784\approx \boldsymbol{1.478}\\ \\ and\ median =\frac{1.31+1.49}{2}=\frac{2.8}{2}=1.4$
