breakin’ a sweat, inc., a manufacturer of elliptical machines, has compiled data related to factory maintenance costs for the past six months. the maintenance cost and related machine hours were entered in microsoft excel. given the following regression analysis output, which of the following statements is false? (assume a relevant range of 0-15,000 machine hours)

r squared 0.95
intercept coefficient 4000
x variable 1 coefficient 0.80

(a) if plotted on a graph, the collected data points would lie near the line created with the above regression analysis output.
(b) an estimate of factory maintenance costs at an activity level of 8,000 machine hours is $11,600.
(c) if machines hours are zero in a given month, estimated factory maintenance costs would equal $4,000.
(d) the cost formula represented by the above output is estimated factory maintenance costs-$0.80 (number of machine hours) + $4,000.
(e) multiplying 0.80 by the number of anticipated machine hours would yield an estimate of total variable factory maintenance costs for that activity level
