Answer: C
Step-by-step explanation:
<u>Given:</u>
Sample size (n) = 50
x = 12
Confidence level = 90%
α = 1 − 0.90 = 0.10
α/2 = 0.05
(from standard normal table)
90% Confidence interval is,
Therefore, 90% confidence interval for the true proportion of sophomores who favour the adoption of uniforms is C
Yes, this is a typical pythagorean triad.
Since the theorem is:
And by inspection,
would be the hypotenuse,
25 = 9 + 16
RHS = 9 + 16 = 25 = LHS
Therefore, we have proved that the values fit into pythagoras' theorem, which means that the triangle is a right triangle (that is the central idea of this theorem).
