Need some geometry help
GenaCL600 [577]
Check the picture below.

that means

angle AFB is 27 + 2 = 29

angle BFC is 2(27) + 12 = 66

and angle CFD is 2(27) or 54

so hmmmm, you'd know which one isn't there.

In a random sample of 600 cars making a right turn at a certain intersection, 157 pulled into the wrong lane. Test the hypothesi
nevsk [136]

Answer:

a)

<em>The statistic value |Z| = 2.053 > 1.96 at 0.05 Level of significance</em>

<em>Null hypothesis is rejected</em>

<em>Alternative hypothesis is Accepted</em>

<em> Actually 30% of all drivers make not this mistake at the given intersection</em>

<em>b)</em>

<em>The test statistic value |Z| = 2.053 >2.576 at 0.01 Level of significance</em>

<em>Null hypothesis is Accepted</em>

<em> Actually 30% of all drivers make this mistake at the given intersection</em>

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given Population proportion = 30% or 0.30

Given data In a random sample of 600 cars making a right turn at a certain intersection, 157 pulled into the wrong lane

sample proportion

          p^{-} = \frac{x}{n} = \frac{157}{600} = 0.2616

<em>Null hypothesis:- H₀: p = 0.30</em>

<em>Alternative  hypothesis : H₁:p≠0.30</em>

<u><em>Step(ii):-</em></u>

a)

<em>Test statistic </em>

        Z = \frac{p^{-}-P }{\sqrt{\frac{p(1-p)}{n} } }

      Z = \frac{0.2616-0.30 }{\sqrt{\frac{0.30(1-0.30)}{600} } }

     Z =  -2.053

<em>     |Z| = |-2.053| = 2.053</em>

<em>Level of significance = 0.05</em>

<em>Z₀.₀₅ = 1.96</em>

<em>The calculated value |Z| = 2.053 > 1.96 at 0.05 Level of significance</em>

<em>Null hypothesis is rejected</em>

<em>Alternative hypothesis is Accepted</em>

<u><em>Conclusion:</em></u><em>-</em>

<em> Actually 30% of all drivers make not this mistake at the given intersection</em>

<em>b)</em>

<em>Given level of significance  = 0.01</em>

<em>Z₀.₀₁ = 2.576</em>

<em>The calculated value |Z| = 2.053 >2.576 at 0.01 Level of significance</em>

<em>Null hypothesis is Accepted</em>

<em> Actually 30% of all drivers make this mistake at the given intersection</em>
