Determine the intercepts of the line that passes through the following points. (-5,-7) (0,-5) (5,-3)
MAVERICK [17]
To find the y intercept you use this equation:

y2 - y1

Same for x intercept:

x2 - x1

Pick two points, put in the values, and solve.

(-5,-7) and (0,-5)

-5 - (-7) = 2
0 - (-5) = 5

The y intercept is (0,2)
The x intercept is (5,0)

Hope this helps! :)

The owners of an industrial plant want to determine which of two types of fuel (gas or electricity) will produce more useful ene
madreJ [45]

Answer:

d. H0: (\mu_e - \mu_g) = 0 vs. Ha: (\mu_e - \mu_g) \neq 0

Step-by-step explanation:

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".  

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".  

On this case the Management try to determine if there is a difference in the average investment/quad between using electricity and using gas. So this needs to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.  

Null hypothesis :\mu_e = \mu_g

Alternative hypothesis: \mu_e \neq \mu_g

Or equivalently:

Null hypothesis :\mu_e - \mu_g = 0

Alternative hypothesis: \mu_e - \mu_g \neq 0

Other important thing is that on the alternative hypothesis we never can have the symbol equal.  

So on this case the best options is:

d. H0: (\mu_e - \mu_g) = 0 vs. Ha: (\mu_e - \mu_g) \neq 0
