Confidence interval of a population proportion is given by p^ + or - sqrt(p^(1 - p^)/n); where p^ = 450/600 = 0.75 and n = 600
99.7% convidence interval = 0.75 + or - 2.96 x sqrt(0.75(1 - 0.75)/600) = 0.75 + or - 2.96 x sqrt(0.75(0.25)/600) = 0.75 + or - 2.96 x 0.0177 = 0.75 + or - 0.0524 = 0.697 to 0.803 = 69.7% to 80.3%
Y=x blue point of a number line
Answer:
148°
Step-by-step explanation:
it is very close to the 150 line and the option closest to 150 is 148
19=10%X. 19/.10=190. X=190 :)
Because when you build things with real wood and tools, negative length has no physical meaning. There are still two square roots, but we ignore the one that's not useful.
