Answer:

Talia needs to factor -1 out of one of the two binomials

Step-by-step explanation:

She could take:

3x(5x - 1) + 4(-5x + 1)

and rewrite it as:

3x(5x - 1) - 4(5x - 1)

= (3x - 4)(5x - 1)

`H_0: p = 0.63`

The test statistic, rounded to 2 decimal places is equal to

<h3>How to calculate value of the test statistic?</h3>

For this sample, the hypothesis is given by:

H₀: μ₁ ≤ μ₂

H₁: μ₁ > μ₂

Assuming this sample has a normal distribution, we would use a pooled z-test to determine the value of the test statistic:

Substituting the given parameters into the formula, we have;

$z = \frac{\frac{96}{150} \;-\;0.63}{\sqrt{0.63\; +\; \frac{1\;-\;0.63}{150}} }\\\\z = \frac{0.64 \;-\;0.63}{\sqrt{0.63\; +\; \frac{0.37}{150}}}\\\\z = \frac{0.01}{\sqrt{0.63\; +\; 0.0025}}\\\\z = \frac{0.01}{\sqrt{0.6325}}\\\\$

z = 0.01/0.7953

z = 0.013.
