A biology class conducts a bird count every week during the semester. Using the number of species counted each​ week, a student finds a​ 95% confidence interval of​ (16.34,18.69) for the mean number of species counted. Knowing that species have to be whole​ numbers, the student reports that​ 95% of the bird counts saw​ 16, 17, or 18 species. Comment on the​ student's report.

Answer:

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.
