12.3.11 Find (a) the range, and (b) the standard deviation for the given sample.
84.48, 84.37, 84.25, 85.02, 85.02, 85.28, 84.64, 84.33, 85.67 O
(a) Find the range of the given sample.
Range = 1.42
(Simplify your answer. Type an integer or a decimal.)
(b) Find the standard deviation of the given sample.
S =
(Simplify your answer. Type an integer or decimal rounded to the nearest hundredth as needed.)

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.
