A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 70 specimens and counts the number of seeds in each. Use her sample results (mean = 15.9, standard deviation = 7.7) to find the 90% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places.  90% C.I. =
