Construct a 95% confidence interval for a population proportion using repeated tests of significance to develop an interval of p

lausible values based on a sample proportion of 0.52 from a sample of 300. Use two-sided tests with the following values under the null hypothesis to find the needed corresponding p-values to construct the interval.
p-value p-value
Null p-value Null P-value
Proportion = 0.53 Proportion = 0.54
Proportion = 0.45 Proportion = 0.46
Proportion = 0.47 Proportion = 0.48
Proportion = 0.49 Proportion = 0.50
Proportion = 0.51 Proportion = 0.55
Proportion = 0.56 Proportion = 0.57
Proportion = 0.58 Proportion = 0.59

Bad White [126]

Answer:

4.9\%

Step-by-step explanation:

we know that

To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area

Let

x ----> the area of the hole

y ----> the area of the playing game

so

P=\frac{x}{y}

we have

y=16\ ft^2

<em>Find the area of the hole</em>

The area of the circle (hole) is equal to

A=\pi r^{2}

we have

r=1/2=0.5\ ft ----> the radius is half the diameter

assume

\pi =3.14

substitute

A=(3.14)(0.5)^{2}

A=0.785\ ft^2

<em>Find the probability</em>

P=\frac{x}{y}

we have

x=0.785\ ft^2

y=16\ ft^2

substitute

P=\frac{0.785}{16}

P=0.0491

Convert to percentage

0.0491*100=4.91\%

Round to the nearest tenth

4.9\%

Find the distance between the points (-1,-7) and (8,-9). The answer must be a whole number or a fully simplified radical express
ruslelena [56]

Answer:

The answer is

<h2>\sqrt{85}  \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-1,-7) and (8,-9)

The distance between them is

d =  \sqrt{( { - 1 - 8})^{2}  +  ({ - 7 + 9})^{2} }  \\  =  \sqrt{ ({  - 9})^{2} +  {2}^{2}  }  \\  =  \sqrt{81 + 4}

We have the final answer as

\sqrt{85}  \:  \:  \: units

Hope this helps you
