Answer:

Yes and Yes

Step-by-step explanation:

Simply put, a z-score (also called a standard score) gives you an idea of how far from the mean a data point is. But more technically it's a measure of how many standard deviations below or above the population mean a raw score is. A z-score can be placed on a normal distribution curve.

Stainless steels are frequently used in chemical plants to handle corrosive fluids, however, these steels are especially suscept

Ira Lisetskai [31]

Answer: 95% confidence interval would be (0.344,0.456).

Step-by-step explanation:

Since we have given that

n = 295

x = 118

so, $\hat{p}=\dfrac{x}{n}=\dfrac{118}{295}=0.4$

At 95% confidence, z = 1.96

So, margin of error would be

$z\times \sqrt{\dfrac{p(1-p)}{n}}\\\\=1.96\times \sqrt{\dfrac{0.4\times 0.6}{295}}\\\\=0.056$

so, 95% confidence interval would be

$\hat{p}\pm \text{margin of error}\\\\=0.4\pm 0.056\\\\=(0.4-0.056,0.4+0.056)\\\\ =(0.344,0.456)$

Hence, 95% confidence interval would be (0.344,0.456).

The of -6 is 6, because it is 6 units from zero on

Ilya [14]

Answer: The absolute value of -6 is 6 because it is 6 units away from zero on the number line

In terms symbols, we use vertical bars like this

|-6| = 6

to represent absolute value. Absolute value is distance from zero on a number line. Negative distance is not possible.

What are the units for the spring constant, k?

svlad2 [7]

The spring constant, k, in Hooke's Law has units of Newton per meter since it is a constant for the force applied per unit of length. The spring constant measures how strong and stiff the spring is. Hope this answers the question. Have a nice day.
