A study of king penguins looked for a relationship between how deep the penguins dive to seek food and how long they stay underwater. For all but the shallowest dives, there is a linear relationship that is different for different penguins. The study report gives a scatterplot for one penguin titled, “The relation of dive duration (DD) to depth (D).” Duration DD is measured in minutes, and depth D is in meters. The report then says, “The regression equation for this bird is DD=2.69+0.0138D.DD=2.69+0.0138D.
(a) What is the slope of the regression line? (Enter your answer rounded to four decimal places.)
slope =
(b) On average, if the depth of the dive increases by one meter, what is the increase in the diving duration? (Enter your answer rounded to four decimal places.)
increase in duration =
minutes
(c) According to the regression line, how long does a typical dive to a depth of 192192 meters last? (Enter your answer rounded to three decimal places.)
length of dive =
minutes

(5.26) An owner of a home in the Midwest installed solar panels to reduce heating costs. After installing the solar panels, he measured the amount of natural gas usedy (in cubic feet) to heat the home and outside temperaturer( in degree- days, where a day's degree-days are the number of degrees its average temperature falls below 65 F) over a 23-month period.

Response Questions Part A I& B Measuring tree height is not an easy task. How well does trunk diameter predict tree trees in an old-growth forest in Canada provides us with the information: The mean tree height is 15.6 meters (m) with standard deviation 13.4m; the mean diameter, measured at "breastheight (1.3m above ground), is 23.4 centimeters (cm), and the standard deviation is 23.5 cm. The correlation between the height and diameter is very high:r-0.96 A survey of 958 live...
