Researchers studying the relationship between body length (L,
mm) and number of eggs (E, count) in goldfish calculated the
following equation based on one sample:
πΈΒ―=10ππππ +0.2ππππ /ππβ πΏ
They took a second from the same population, and found that the
covariance between E and L, πππ£(πΏ,πΈ) ,in the second
sample was 0.25 times as large as in the first study, but the
variance in length π 2πΏ was the same as in the first
sample. They also found the average number of eggs per fish was 5
eggs larger in the second sample
What regression slope would the researchers calculate based on
the second sample?
Select one:
a. 2.5 eggs/mm
b. 15 eggs/mm
c. 0.05 eggs/mm
d. 0.1 eggs/mm
e. 4 eggs/mm
