b) False

One of the assumptions of OLS regression is that the error terms are exponentially distributed

Answer : A) True

The number of people live in circular region are 319,990

Step-by-step explanation:

A circular region with a 4-mile radius has a population density of about 6366 people per square mile.

[tex[\text{Population density }=6366\text{ people/mi}^2[/tex]

Area of circular region = πr²

where, radius (r) = 4 miles

Area of circular region = π x 4²

                                     = 16π mi²

We need to find number of people who live in the circular region .

Number of people = Population density x Area of region

Number of people = 6366 x 16π

                               = 319,990

Hence, The number of people live in circular region are 319,990
