Concept explainers
The data given in the previous exercise on x = Call-to- shock time (in minutes) and y = Survival rate (percent) were used to compute the equation of the least-squares line, which was
ŷ = 101.33 − 9.30x
The newspaper article “FDA OKs Use of Home Defibrillators” (San Luis Obispo Tribune, November 13, 2002) reported that “every minute spent waiting for paramedics to arrive with a defibrillator lowers the chance of survival by 10 percent.” Is this statement consistent with the given least-squares line? Explain.
