Question

The effects of a toxic pollutant upon fish was examined by placing fish in a solution of water with various concentrations of the pollutant. The time (in minutes) until the fish showed distress was recorded at which the fish were removed from the container. A total of 18 different experiments were performed. Note that the pollutant is measured on a logarithmic scale where a change of one unit represents an increase of 10 fold in the pollution concentration. The computer output appears below:

a.
Y= 7.56 - 1.03(logpollut)
b.
Y= - 1.03 + 7.56(logpollut)
c.

Y= 3.82 - 2.34(logpollut)

d.

Y= -2.34 + 3.82(logpollut)

Explanation / Answer

Model - 2.21

Error - 6.45

Correlation total - 8.670

Intercept- 3.82

Log Pollout- -2.34

So regression model

Y= Intercept + Log poll out

= 3.82-2.34

C answer
