Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Upper H 0: pequals0.6 versus Upper H 1: pgreater than0.6 nequals200; xequals135, alphaequals0.05 Is np 0 (1 minus p 0 )greater than or equals10.

Use technology to find the P-Value.

Answers

Answer 1

Answer:

Step-by-step explanation:

From the given information:

The null and the alternative hypothesis can be well written as:

[tex]H_o:P=0.6[/tex]

[tex]H_1:P>0.6[/tex]

Given that:

n = 200

x = 135

Alpha ∝ = 0.05 level of significance

Then;

⇒ [tex]n \times p\times (1-P)[/tex]

= 200 × 0.6 × (1 -0.6)

= 200 × 0.6 × 0.4

= 48 ≥ 10

The sample proportion [tex]\hat P = \dfrac{x}{n}[/tex]

[tex]= \dfrac{135}{200}[/tex]

= 0.675

The test statistics [tex]Z = \dfrac{\hat P - P}{\sqrt{ \dfrac{P(1-P)}{n} }}[/tex]

[tex]Z = \dfrac{0.675 - 0.6}{\sqrt{ \dfrac{0.6 \times 0.4}{200} }}[/tex]

[tex]Z = \dfrac{0.075}{\sqrt{ \dfrac{0.24}{200} }}[/tex]

Z = 2.165

The P-value = P(Z > 2.165)

= 1 - P(Z < 2.165)

From the z tables

= 1 - 0.9848

= 0.0152

Reject the null hypothesis since P-Value is lesser than alpha. ( i.e. 0.0152 < 0.05).

Thus, there is enough evidence to conclude that the value of the population proportion is greater than 0.6

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

To find the slope, you need to find any 2 points on the line.

In this case, there is a point at (0, 0), and a point at (4, 3).

Formula for slope: [tex]m = \frac{rise}{run}[/tex]

The rise is the change in the y axis from point 1, in this case (0, 0), to point 2, in this case (4, 3). The run is the change in the x axis from point 1 to point 2.

You can subtract the point 1 values from point 2 to get the rise and run:

[tex]m = \frac{3 - 0}{4 - 0} = \frac{3}{4}[/tex]

f(x)=-x²-2x-8 determine the vertex

Answers

Answer:

vertex = (- 1, - 7 )

Step-by-step explanation:

Given a parabola in standard form, f(x) = ax² + bx + c (a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = - x² - 2x - 8 ← is in standard form

with a = - 1 and b = - 2, then

[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{-2}[/tex] = - 1

Substitute x = - 1 into f(x) for corresponding y- coordinate

f(- 1) = - (- 1)² - 2(- 1) - 8 = - 1 + 2 - 8 = - 7

vertex = (- 1, - 7 )

For a quadratic function like this, the vertices are points of symmetry.

PLZZZZZZZZZZZZZZZZZZZ HELP THIS DUE TODAY AND NO ONE HELPING I SWEAR THE PEOPLE ANSWER THESE QUESTIONS WERE TROLLING PLZ I NEED THIS DONE!!!TEXT: The first effect of the creation of the 13 colonies was that Britain grew very rich. Each colony now had productive farms and new towns growing as trading posts. Britain profited from these by taxation. Everything grown, bought or sold in the American Colonies was somehow taxed by Britain.Another effect was the British Colonies became destinations for thousands of immigrants from England and elsewhere in Europe. Wealthy Europeans were eager to claim new land for plantations or make fortunes from trade in the new cities. Middle-class European farmers hoped they could get new farmland of their own. Many poor English and Scots-Irish settlers hoped they could find better lives in America working as indentured servants and hopefully purchasing land of their own someday.Every new English colony was a new disaster for the Native Americans. The forests they hunted were cut down to make way for farms and plantations. More and more tribes became pushed off their land, either being cheated by false negotiations, or forced out with violence. When tribes fought back, the English settlers would retaliate harshly with gunfire and arson, burning entire villages to the ground. Worse still was the invisible killer that British settlers brought with them: diseases like smallpox and plague, which spread among native tribes quickly and for which they had no immunity or treatments. Sometimes, colonists would give infected blankets to natives to spread diseases on purpose. Ultimately for the native tribes, the effects of British settlement in America were tragic and irreversible. By the mid 1700s, most tribes had nearly vanished from the Atlantic coast.The final effect of the British Colonies was the introduction of slavery to North America. The first kidnapped Africans in the American Colonies were brought to Jamestown as slaves to work in the new tobacco plantations. Slavery would spread throughout the new colonies, with cities as far north as New York being used as trading posts for slave auctions. Mainly however, slavery was much more concentrated in the southern colonies, which had large tobacco and rice plantations requiring many laborers. In the Southern Colonies, African people were simply considered property. Laws in Maryland only referred to Africans in terms of planters property rights. A Virginia law in 1642 punished people for hiding runaway slaves or indentured servants. Free blacks were eventually permitted to live and own property in northern colonies, and slavery in the north slowly became outlawed. In the south, however, the plantation economies of the colonies depended almost completely on slave labor.17.
