Answer:

So the value of the test statistic is -0.85.

Step-by-step explanation:

We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.

We get that:

$n=1800\\\\p_1=53\%=0.53\\\\p_2=54\%=0.54\\$

We calculate the standar deviation:

$\sigma=\sqrt{\frac{0.53 \cdot (1-0.53)}{n}}=\sqrt{\frac{0.53 \cdot 0.47}{1800}}=0.01176$

We calculate the value of the test statistic:

$z=\frac{p_1-p_2}{\sigma}=\frac{0.53-0.54}{0.01176}=-0.85$

So the value of the test statistic is -0.85.

What is the slope of the line through (-1,4) and (5,2)

butalik [34]

Answer:

Slope (m) = $-\frac{1}{3}$

Step-by-step explanation:

Use the following equation:

Slope $(m) = \frac{y_2 - y_1}{x_2 - x_1}$

Let:

$(x_1 , y_1) = (-1 , 4)\\(x_2 , y_2) = (5 , 2)$

Plug in the corresponding numbers to the corresponding variables:

$m = \frac{2 - 4}{5 - (-1)} = \frac{2 - 4}{5 + 1} = \frac{-2}{6}$

Simplify. Divide common factors from both the numerator and denominator:

$\frac{(-\frac{2}{6})}{\frac{2}{2} } = -\frac{1}{3}$

$-\frac{1}{3}$ is your answer.
