An article describes an experiment to determine the effectiveness of mushroom compost in removing petroleum contaminants from so
alexgriva [62]

Solution :

Let p_1 and p_2  represents the proportions of the seeds which germinate among the seeds planted in the soil containing 3\% and 5\% mushroom compost by weight respectively.

To test the null hypothesis H_0: p_1=p_2 against the alternate hypothesis  H_1:p_1 \neq p_2 .

Let \hat p_1, \hat p_2 denotes the respective sample proportions and the n_1, n_2 represents the sample size respectively.

$\hat p_1 = \frac{74}{155} = 0.477419

n_1=155

$p_2=\frac{86}{155}=0.554839

n_2=155

The test statistic can be written as :

$z=\frac{(\hat p_1 - \hat p_2)}{\sqrt{\frac{\hat p_1 \times (1-\hat p_1)}{n_1}} + \frac{\hat p_2 \times (1-\hat p_2)}{n_2}}}

which under H_0  follows the standard normal distribution.

We reject H_0 at 0.05 level of significance, if the P-value or if |z_{obs}|>Z_{0.025}

Now, the value of the test statistics = -1.368928

The critical value = \pm 1.959964

P-value = $P(|z|> z_{obs})= 2 \times P(z< -1.367928)$

                                     $=2 \times 0.085667$

                                     = 0.171335

Since the p-value > 0.05 and $|z_{obs}| \ngtr z_{critical} = 1.959964$, so we fail to reject H_0 at 0.05 level of significance.

Hence we conclude that the two population proportion are not significantly different.

Conclusion :

There is not sufficient evidence to conclude that the \text{proportion} of the seeds that \text{germinate differs} with the percent of the \text{mushroom compost} in the soil.

Answer:

D. \frac{4x^{2} \sqrt{29}}{29}

Step-by-step explanation:

Given the expression:

 \frac{40x^{2} \sqrt{x^{12} } }{10x^{2} \sqrt{29x^{8} } }

divide by the common factor to have;

\frac{4\sqrt{x^{12} } }{\sqrt{29x^{8} } } = \frac{4(x^{12}) ^{\frac{1}{2} } }{(29x^{8}) ^{\frac{1}{2} } }

        = \frac{4x^{6} }{\sqrt{29}x^{4}  }

        = \frac{4x^{2} }{\sqrt{29} }

Rationalize the denominator, we have;

\frac{4x^{2} }{\sqrt{29} } x \frac{\sqrt{29} }{\sqrt{29} }

So that,

\frac{4x^{2} \sqrt{29} }{29}

Thus,

\frac{40x^{2} \sqrt{x^{12} } }{10x^{2} \sqrt{29x^{8} } } = \frac{4x^{2} \sqrt{29} }{29}

The correct option is D.
