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.

Westfalls is 7 miles south of edenville and Concord is 13 mile west of westfalls. What is the distance from edenville to Concord
Lelu [443]

Answer:

D_x\approx14.8mile

Step-by-step explanation:

From the question we are told that

Distance between Edenville and Westfalls D_1=7

Distance between  Westfalls  and Concord D_2=13

Generally the equation for Pythagoras is mathematically given by

D_x^2=D_1^2+D_2^2

D_x^2=7^2+13^2

D_x=\sqrt{ 7^2+13^2}

D_x=14.76482306mile

The distance b/w Edenville to Concord is

D_x\approx14.8mile
