$6340
Step-by-step explanation:
First figure out what 6.5% of 4000 is by multiplying not dividing because dividing will give you a way bigger number.
4000 x 6.5%=260
260 x 9=2340
2340+4000=6340

A student finds a 95% confidence interval of (16.34,18.69) for the mean number of species counted. This is a valid interval because the mean number of species or any population mean does not necessarily have to be a whole number, as stated by the student.
This given confidence interval of (16.34,18.69) helps us to simply estimate the mean species counted.
