Farmer Brown and Farmer Green were talking over their fence one afternoon. Farmer Brown said, "If you gave me one of your cows,
qaws [65]

Farmer Brown has 5 cows and farmer Green has 7 cows

Step-by-step explanation:

Let the no. of cows farmer brown has be 'b'

Let the no. of cows farmer green has be 'g'

Given that,

B+1 = G-1

G = B + 2

G+1 = 2(B-1)

G+1 = 2B - 2

G = 2B -3

B + 2 = 2B - 3

2 + 3 = 2B - B

B = 5

G = B +2

G = 5 + 2

G = 7

Farmer Brown has 5 cows and farmer Green has 7 cows

Pls help I<br> This is geometry Been struggling due soon show work

Triangles have 180^{\circ} in total, so the sum of all the angles should be 180^{\circ}

First triangle

180 = 90 + (x + 5) + (2x - 2)\\180 = 90 + x + 5 + 2x - 2\\180 - 90 - 5 + 2 = x + 2x\\87 = 3x\\x = 29^{\circ}

Second triangle

180 = (x + 40) + (2x - 5) + (3x - 17)\\180 = x + 40 + 2x - 5 + 3x - 17\\180 - 40 + 5 + 17 = x + 2x + 3x\\162 = 6x\\x = 27^{\circ}

You conduct a simulation regarding which team spectators at a football game support. Your null hypothesis is that there are equa
Llana [10]

Answer:

As the <em>p</em>-value is too small the null hypothesis will be rejected concluding that there is a higher proportion of people supporting the home team.

Step-by-step explanation:

The hypothesis to determine which team spectators at a football game support is:

<em>H₀</em>: There are equal proportions of people supporting the home team and the visiting team, i.e. <em>p</em>₁ = <em>p</em>₂.

<em>Hₐ</em>: There is a higher proportion of people supporting the home team than the visiting team, i.e. <em>p</em>₁ > <em>p</em>₂.

A <em>z</em>-test for difference between proportions can be used to perform the test.

The test statistic is:

z=\frac{\hat p_{1}-\hat p_{2}}{\sqrt{P(1-P)\frac{1}{n_{1}}+\frac{1}{n_{2}}}}}

Th decision rule is:

If the <em>p</em>-value of the test is less than the significance level <em>α </em>then the null hypothesis will be rejected and vice-versa.

The commonly used significance levels are 0.01, 0.05 and 0.10.

The <em>p</em>-value of the test is computed as, <em>p</em> = 0.002.

The <em>p</em>-value of the test is less than all the significance level.

Thus, the null hypothesis will be rejected at any of the three significance level.

Conclusion:

As the <em>p</em>-value is too small the null hypothesis will be rejected concluding that there is a higher proportion of people supporting the home team.
