Question

Transcribed Image Text:Suppose an animal scientist, Dr. Dew believes that birth weight (in kg) explains the variation
in the length of gestation (in days until birth) for various mammals. To support this fact, he
collected data and found out that when the birth weight was x =
length of gestation was y =
Hint: E,(x; – 7)² = 540, 916.8, E, (y: – 9)² = 195, 233, and E:(yi – ŷ)² = 181, 018.
