Do men’s voting preferences differ significantly from women’s voting preferences?"" Use a level of significance of α = 0.05. Whi
baherus [9]

Answer:

<em>H₀</em>: The voting preference of men and women are not different.

<em>Hₐ</em>: The voting preference of men and women are not different.

Step-by-step explanation:

A hypothesis test for two proportions can be used to determine whether the preference of men differ from women in case of voting.

A Chi-square test contingency table can be used to perform the test.

The hypothesis can be defined as:

<em>H₀</em>: The voting preference of men and women are not different.

<em>Hₐ</em>: The voting preference of men and women are not different.

The test statistic is:

\chi^{2}=\frac{Row\ total\times Column\ total}{N}

Decision rule:

If the <em>p</em>-value of the Chi-square test statistic is less than the significance level <em>α</em> = 0.05 then the null hypothesis will be rejected. And if the <em>p</em>-value is more than the significance level then the null hypothesis will not be rejected.

Why equals 3/4 X -12 and why equals negative 4X - 31
Helga [31]

Answer:

  (x, y) = (-4, -15)

Step-by-step explanation:

Perhaps you want the solution to ...

  y = 3/4x -12

  y = -4x -31

Equating the two expressions for y gives ...

  3/4x -12 = -4x -31

  3/4x = -4x -19 . . . . . add 12

  3x = -16x -76 . . . . . multiply by 4

  19x = -76 . . . . . . . . . add 16x

  x = -76/19 = -4 . . . . divide by 19

  y = (3/4)(-4) -12 = -15 . . . . use the first equation to find y

The solution to this system of equations is ...

  (x, y) = (-4, -15)

Answer:

13

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

   = ( -9-4)/(6-7)

   = -13/-1

  = 13
