Answer:

REQUIRED TEST STATICS IS 35.19

Step-by-step explanation:

total size of sample = 10,000

men women

voted 2777 3466

did not vote 1444 2313

By chi square test we can find the relationship between gender and participation in the election

$X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}$

where

a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

$X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}$

$X^2 = = 35.159$

White raven [17]

Answer:

29.92 m² (nearest hundredth)

Step-by-step explanation:

$\textsf{Area of a sector}=\dfrac{\theta}{360\textdegree}\pi r^2$

$\implies \textsf{area}=\dfrac{30}{360\textdegree}\pi \cdot 5.5^2=\dfrac{121}{48}\pi \textsf{ m}^2$

Area of rectangle = width × length

⇒ area = 4 × 5.5 = 22 m²

Total area = area of sector + area of rectangle

⇒ total area = $\dfrac{121}{48}\pi +22$ = 29.91943148... = 29.92 m² (nearest hundredth)
