    A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 42 specimens and counts the number of seeds in each. Use her sample results (mean = 79.1, standard deviation = 10.3) to find the 95% 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.   95% C.I. =

    A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 60 specimens and counts the number of seeds in each. Use her sample results (mean = 17.1, standard deviation = 16.4) to find the 95% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
