Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 600 grams while babies born after a gestation period of 40 weeks have a mean weight of 3300 grams and a standard deviation of 445 grams. If a 34-week gestation period baby weighs 3100 grams and a 41-week gestation period baby weighs 3600 grams, find the corresponding z-scores. Which baby weighs more relative to the gestation period?

250

step-by-step explanation:

hi there!

the answer will be d: 2

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.
