In 1965, about 44% of the U. S. adult population had never smoked cigarettes. A national health survey of 1472 U. S. adults, presumably selected randomly, during 2010 revealed that 677 had never smoked cigarettes. Suppose you wished to test whether there has been a change since 1965 in the proportion of U. S. adults who have never smoked cigarettes. You test the hypotheses H 0 : p = 0.44 , H α : p ≠ 0.44 . The P ‑value of the test is:

P < 0.44 \, \, or \, \, P> 0.44 )

Step-by-step explanation:

From the question , we were given the following details:

44% of the U.S. adult population had never smoked cigarettes. This means that the proportion of the population is 44/100=0.44

There is need for us to test whether there has been a change, of which the change could be either in the form of increase or decrease.

Thus, below is our hypothesis :

H_o: P = 0.44

H_1: P \neq 0.44

Thus,  P < 0.44 \, \, or \, \, P> 0.44 )

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option

step-by-step explanation: w

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
