Question



A study of king penguins looked for a relationship between how deep the penguin to seek food and how they stay For all nut the there is linear relationship that is different for different penguins. The study report gives a for one penguin "The relation of dive duration (DD) to depth (D) Duration DD is measured minutes and depth D is in meters. The report than says, The regression equation for this bird is DD = 2.23 + 0.0143 D. (a) What is the slope of the regression line? (b) According to the regression line how long does a typical dive to a depth of 125 meters fast?

Explanation / Answer

Given : The regression line is ,

DD = 2.23 + 0.0143 D

a ) The slope of the regression line = 0.0143

b ) For D = 125

Therefore ,

DD = 2.23 + 0.0143 * 125 = 4.0175
