3.2.14 Recall that researchers also conducted a follow-up study predicting the outcomes of races in the House of Representatives with 189 correct predictions out of 279. a. Use a simulation and the 2SD method to compute a 95% confidence interval. b. Use a theory-based approach to generate the 95% confidence interval for these data. c. Compare the intervals you computed in parts (a) and (b), why are they similar

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
