What does the scatter chart indicate about the relationship between the weight and
price of these bicycles?
(1b) Choose one:
The - ANSWER ✅✅✅✅(1a) Chart (i): Weight = x-axis, Price = y-axis
(1b) negative
(b) y = 28,818.00 - 1,439.01x
(c) Its either (i) or (ii)
(d) 86.37%
(e) $4,355 (28,818.00 - 1,439.01(17 pounds) = 4,355))
QUIZ 2 (Question #2)
The regional transit authority for a major metropolitan area wants to determine whether
