Suppose that a regression line for some data transformed with logarithms predicts that when x equals 4, log(y) will equal 3.331. what does the regression line predict y will equal when x equals 4? round your answer to the nearest whole number.

a. 101

b. 13

c. 3

d. 2143

Option D

The regression line predicts that at x = 4, y equals 2143

Solution:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

We need to find the value of 'y' when x = 4

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

On rounding to nearest whole number, we get 2143

Thus Option D is correct

won't that be plagrisim thought?
