Question

Suppose that a regression line for some data transformed with logarithms

predicts that when x equals 9, log() will equal 3.992. What does the

regression line predict ý will equal when x equals 9? Round your answer to the

nearest whole number.

O A. 36

O B. 6447

O C. 9817

O D. 4

Answer 1

correct option is C. 9817

Explanation:

given data

x = 9

log(y) = 3.992

solution

we know that we have given that when x = 9

so log (y) = 3.992 .........................1

so now we take here anti log on the both side of given equation that is

put the value of antilog in equation 1 we get

y =
`10^(3.992)`

solve it we get y that is

y = 9817.47

y = 9817

so correct option is C. 9817
