A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 51 specimens and counts the number of seeds in each. Use her sample results (mean = 75.8, standard deviation = 9.8) to find the 99% 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). 99% C.I. =  Answer should be obtained without any preliminary rounding.
