Astudy was done on the mortality (live vs. die) of two major hospitals: carebetter and treatmore. data were collected over a period of time from five major illnesses and it was found that carebetter does better overall (i. e., has a smaller percentage of deaths). however, in each of the five illnesses separately, treatmore does better. which of the following is correct? a this is an example of simpson's paradox. b "illness" is a lurking variable in this example. c both (a) and (b) are correct. d this is an example of a negative association between variables. e this situation is mathematically impossible.

true? is that what you're asking or do you mean something else?

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
