A study collects birth weights (in units of grams) of infants whose mothers did not smoke and separates them by paternal smoking status. The birth weights for infants with nonsmoking fathers are {3250, 3380, 2910, 3100, 3300}\{3250,\;3380,\;2910,\;3100,\;3300\}. The birth weights for infants with smoking fathers are {2980, 2850, 3050, 2900, 2760}\{2980,\;2850,\;3050,\;2900,\;2760\}. Determine the sample standard deviation for each group (report to one decimal place).
