Answer:

The slope of ZW is \frac{2}{5}

The lenght of ZY is \sqrt{29}

Quadrilateral WXYZ is a square

Step-by-step explanation:

<u>Statements</u>

<u>case A)</u> The slope of ZW is \frac{2}{5}

The statement is True

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

Z(-3,1),W(2,3)

substitute

m=\frac{3-1}{2+3}

m=\frac{2}{5}

<u>case B)</u> The slope of YX is -\frac{5}{2}

The statement is False

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

Y(-1,-4),X(4,-2)

substitute

m=\frac{-2+4}{4+1}

m=\frac{2}{5}

<u>case C) </u>The lenght of ZY is \sqrt{29}

The statement is True

we know that

the formula to calculate the distance between two points is equal to

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

we have

Z(-3,1),Y(-1,-4)

substitute

d=\sqrt{(-4-1)^{2}+(-1+3)^{2}}

d=\sqrt{(-5)^{2}+(2)^{2}}

d=\sqrt{29}\ units

<u>case D) </u>The lenght of WX is 5

The statement is False

we know that

the formula to calculate the distance between two points is equal to

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

we have

W(2,3),X(4,-2)

substitute

d=\sqrt{(-2-3)^{2}+(4-2)^{2}}

d=\sqrt{(-5)^{2}+(2)^{2}}

d=\sqrt{29}\ units

<u>case E)</u> Quadrilateral WXYZ is a square

The statement is True

Because  sides ZW and YX are parallel sides (has the same slope)

<u>Slope ZY </u>

we have

Z(-3,1),Y(-1,-4)

m=\frac{-4-1}{-1+3}

m=-\frac{5}{2}

so

ZW and ZY are perpendicular sides (the product of their slopes is equal to minus one)

-\frac{5}{2}*\frac{2}{5}=-1

<u>Slope WX</u>

we have

W(2,3),X(4,-2)

m=\frac{-2-3}{4-2}

m=-\frac{5}{2}

ZY and WX are parallel sides (has the same slope)

<u>distance ZW</u>

we have

Z(-3,1),W(2,3)

d=\sqrt{(3-1)^{2}+(2+3)^{2}}

d=\sqrt{(2)^{2}+(5)^{2}}

d=\sqrt{29}\ units

<u>distance YX</u>

we have

Y(-1,-4),X(4,-2)

d=\sqrt{(-2+4)^{2}+(4+1)^{2}}

d=\sqrt{(2)^{2}+(5)^{2}}

d=\sqrt{29}\ units

The four sides are congruent

case F) YZ=\sqrt{(-3-(-1))^{2}+(1-4)^{2}}

The statement is False

YZ=\sqrt{(-2)^{2}+(-3)^{2}}

YZ=\sqrt{13}  ----> is not correct

the value of YZ is  \sqrt{29}

Have the conditions for inference been met?
alekssr [168]

Answer: the answer is A

Step-by-step explanation: because the original question does not state that the swimmer “randomly selected” the members. It only says the swimmer “selects” 10 members. Therefore, it is A (The sample is not random)

A research group wants to know if the online platform to play Settlers of Catan is being accessed more after the stay at home or
Gre4nikov [31]

Answer:

a) The P-value is 0.

At a significance level of 0.05, there is enough evidence to support the claim that the online platform was accessed significantly more so than before the stay at home order.

b) Effect size d = 0.77

Medium.

Step-by-step explanation:

This is a hypothesis test for the population mean.

The claim is that the online platform was accessed significantly more so than before the stay at home order.

Then, the null and alternative hypothesis are:

H_0: \mu=1000\\\\H_a:\mu> 1000

The significance level is 0.05.

The sample has a size n=108000.

The sample mean is M=1378.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=489.

The estimated standard error of the mean is computed using the formula:

s_M=\dfrac{s}{\sqrt{n}}=\dfrac{489}{\sqrt{108000}}=1.488

Then, we can calculate the t-statistic as:

t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{1378-1000}{1.488}=\dfrac{378}{1.488}=254.036

The degrees of freedom for this sample size are:

df=n-1=108000-1=107999

This test is a right-tailed test, with 107999 degrees of freedom and t=254.036, so the P-value for this test is calculated as (using a t-table):

\text{P-value}=P(t>254.036)=0

As the P-value (0) is smaller than the significance level (0.05), the effect is significant.

The null hypothesis is rejected.

At a significance level of 0.05, there is enough evidence to support the claim that the online platform was accessed significantly more so than before the stay at home order.

The effect size can be estimated with the Cohen's d.

This can be calculated as:

d=\dfrac{M-\mu}{\sigma}=\dfrac{1378-1000}{489}=\dfrac{378}{489}=0.77

The values of Cohen's d between 0.2 and 0.8 are considered "Medium", so in this case, the effect size d=0.77 is medium.
