A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 68 specimens and counts the number of seeds in each. Use her sample results (mean - 39.3, standard deviation = 7.3) 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. %3D 90% C.I. = %3D

Expert Solution
Step 1

We have given that, 

Sample mean (x̄) = 39.3, standard deviation (s)= 7.3 and sample size (n) = 68

Then, 

We will find 90% confidence interval?
