Answer
(a) The scatter plot is shown in the image
(b) $y=4.857x-220.967$. The regression line is shown in the image.
(c) $265$ chirps/min
Work Step by Step
(a) The points on the table are plotted.
(b) The regression line is found using technology, where $m \approx 4.857$ and $b \approx -220.967$.
(c) 100 is input into the equation in (b):
$y = 4.857(100) - 220.967 = 485.7 - 220.967 = 264.733 \approx 265$
