Answer:
(a) 10.0 m²
Step-by-step explanation:
The radius of the inner circle is (2 m -1.1 m) = 0.9 m. The area of each circle is given by the formula ...
A = πr²
so, the difference in areas is ...
shaded = π(2 m)² -π(0.9 m)² = π(4 -0.81) m²
shaded area ≈ 10.0 m²
Solution:
p = 0.25
q = 1 - p = 0.75
x = 127
n = 480
psample = x/n = 127/480 = 0.2645
test statistic, z = (psample - p) / sqrt(pq/n) = (0.2645 - 0.25) / sqrt(0.25×0.75/480) = 0.733
