A botanist wishes to estimate the mean number of seeds for a certain fruit. She samples 11 specimens and finds the average number of seeds is 47 with a standard deviation of 7. Construct a 98% confidence interval for the mean number of seeds for the species using the appropriate critical value to three decimal places.
Enter your answer as equations or as numbers rounded to four decimal places.
