A resident of Bayport claims to the City Council that the proportion of Westside residents

Kazeer [188]

Answer:

The test statistics is $z = -1.56$

The p-value is $p-value = 0.05938$

Step-by-step explanation:

From the question we are told

The West side sample size is $n_1 = 578$

The number of residents on the West side with income below poverty level is $k = 76$

The East side sample size $n_2=688$

The number of residents on the East side with income below poverty level is $u = 112$

The null hypothesis is $H_o : p_1 = p_2$

The alternative hypothesis is $H_a : p_1 < p_2$

Generally the sample proportion of West side is

$\^{p} _1 = \frac{k}{n_1}$

=> $\^{p} _1 = \frac{76}{578}$

=> $\^{p} _1 = 0.1315$

Generally the sample proportion of West side is

$\^{p} _2 = \frac{u}{n_2}$

=> $\^{p} _2 = \frac{112}{688}$

=> $\^{p} _2 = 0.1628$

Generally the pooled sample proportion is mathematically represented as

$p = \frac{k + u}{ n_1 + n_2 }$

=> $p = \frac{76 + 112}{ 578 + 688 }$

=> $p =0.1485$

Generally the test statistics is mathematically represented as

$z = \frac{\^ {p}_1 - \^{p}_2}{\sqrt{p(1- p) [\frac{1}{n_1 } + \frac{1}{n_2} ]} }$

=> $z = \frac{ 0.1315 - 0.1628 }{\sqrt{0.1485(1-0.1485) [\frac{1}{578} + \frac{1}{688} ]} }$

=> $z = -1.56$

Generally the p-value is mathematically represented as

$p-value = P(z < -1.56 )$

From z-table

$P(z < -1.56 ) = 0.05938$

$p-value = 0.05938$

Find the primary solution of cosθ=−0.3 ⁡

Agata [3.3K]

The solution of cos θ = −0.3 is θ = 107.45760312 degrees

Solution:

Given that we have to find the primary solution of $cos \theta = -0.3$

To solve this equation, you must find the unknown (theta)

$cos \theta = -0.3$

Use the inverse of cosine (Arccos) to find the angle measurement (in degrees) of theta

$\theta = arccos (-0.3)$

We know that arccos (-0.3) = 107.45760312 degrees

[ If you reference a unit circle or use a calculator ]

$\theta = 107.45760312^{\circ}$

Therefore solution of cos θ = −0.3 is θ = 107.45760312 degrees

A flower garden is the shape of a circle. The circumference of the garden is 20 meters. What is the area of the garden. Use 3.14

nadezda [96]

Answer: 255 sq meters

Step-by-step explanation:

C = 2(pi)r

C=Circumference=20 Meters

Pi = 3.14 and r is the radius

So, 20=3.14*r

r=20/3.14=6.36942675

Area = 2(pi)r^2

2*3.14*(6.36942675)^2

254.77707

Round to nearest whole number

A=255 sq meters
