Answer:

  D) y = −2/5x

Step-by-step explanation:

In the equation for a line ...

  y = mx +b

the constant 'b' is the y-intercept of the line. The y-intercept is the value of y when x = 0.

The point (0, 0) tells you the y-intercept is 0, or b=0. That reduces the equation to the form ...

  y = mx

The value of m is most easily found if you have a point where x=1. In that case, ...

  y = 1m

  y = m

In the given list of points, there is one that is helpful here: (1, -0.4). That is, the equation for the given points is ...

  y = -0.4x

The answer choices are given as fractions, so you must convert -0.4 to the fraction -2/5.

  y = -2/5x . . . . describes the given points

Blizzard [7]

Answer:

The value of the test statistic is -3.14.

Step-by-step explanation:

Test statistic:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected value, \sigma is the standard deviation and n is the size of the sample.

A company advertises that its cans of caviar each contain 100 g of their product.

This means that \mu = 100

They calculate a sample mean weight of 99 g and a sample standard deviation of 0.9 g. Sample of 8 cans.

This means that X = 99, \sigma = 0.9, n = 8

So the test statistic will be given by:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{99 - 100}{\frac{0.9}{\sqrt{8}}}

t = -3.14

The value of the test statistic is -3.14.
