Anational center for smoking and lung obstruction health statistics data brief published in 2015 (nr. 181) looked at the association between lung obstruction and smoking status in adults 40 to 79 years old. in a random sample of 6927 adults without any lung obstruction, 54.1% never smoked. in a random sample of 1146 adults with lung obstruction (such as asthma or copd), 23.8% never smoked. 10.4 a. find and interpret a point estimate of the difference between the proportion of adults without and with lu obstruction who never smoked b. a 99% confidence interval for the true difference is (0.267, 0.339). interpret. c. what assumptions must you make for the interval it part b to be valid?

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
