In 2010, the Centers for Disease Control and Prevention estimated 9.4% of children under the age of 18 had asthma. They reported the standard error to be 0.35%. Assuming that the sampling distribution is symmetric and bell-shaped, find and interpret a 95% confidence interval.

8.96%   Changes to  8.93%                                                                                      Step-by-step explanation:

9.4 * 0.0035 = 0.0329  where we add this on each side of the 9.4 to show 9.4-0.0329 = 9.3671 and 9.4329  then  9.4329  * 0.95 = 8.961255 = 8.96   then redo 9.3671 * 0.95 =8.898745  the symmetry is 8.961255 -8.898745 =0.06251  8.898745/ (0.06251 /2) nb 006251 distance standard error each side of symmetry line = 8.93% line of symmetry

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb

i think is g(1)=-1.

hope that i can
