Solution :

$H_0: p = 0.5$

$H_a: p > 0.5$

Alpha, α = 0.01

The sample proportion is :

$p'=\frac{x}{n}$

   $=\frac{513}{806}$

   = 0.636

Test statistics, $z=\frac{p'-p}{\sqrt{\frac{pq}{n}}}$

$z=\frac{0.636-0.5}{\sqrt{\frac{0.5\times 0.5}{806}}}$

$z=\frac{0.136}{0.0176}$

z = 7.727

The p value = 0.00001

Here we observe that p value is less than α, and so we reject the hypothesis H_0.

Therefore, there is sufficient evidence,

Ipatiy [6.2K]

Answer:

  see below

Step-by-step explanation:

Any line between two points on the circle is a chord.

Any angle with sides that are chords and with a vertex on the circle is an inscribed angle.

Any angle with sides that are radii and a vertex at the center of the circle is a central angle. Each central angle listed here should be considered a listing of two angles: the angle measured counterclockwise from the first radius and the angle measured clockwise from the first radius.

<h3>1.</h3>

chords: DE, EF

inscribed angles: DEF

central angles: DCF . . . . . note that C is always the vertex of a central angle

<h3>2.</h3>

chords: RS, RT, ST, SU

inscribed angles: SRT, RSU, RST, RTS, TSU

central angles: RCS, RCT, RCU, SCT, SCU, TCU

<h3>3.</h3>

chords: DF, DG, EF, EG

inscribed angles: FDG, FEG, DFE, DGE

central angles: none

<h3>4.</h3>

chords: AE

inscribed angles: none

central angles: ACB, ACD, ACE, BCD, BCE, DCE
