Answer:
For this case we want to test if the average price-to-earnings ratio in the consumer industry is higher than the average price-to-earnings ratio in the banking industry (alternative hypothesis) and the complement would be the null hypothesis:
Null Hypothesis:
Alternative hypothesis:
So the correct option would be:
D. μconsumer > μbanking.
Step-by-step explanation:
Previous concepts
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".

Work:
x^2 + 4x - 4 = 8
x^2 +4x -12 = 0
(x + 6) (x - 2) = 0
x = -6 and 2

Answer:
Why did you poke your eraser it did nothing to you
Step-by-step explanation:
The area of the triangle must be determined. then multiply the area of the triangle by 4lb/1ft2
the equation for the area of a triangle is A = b times h/2
the base equals 5.5 feet and the height is 3 feet.
A = (5.5fttimes 3ft) /2=8.25ft2
4lb mulch is needed for each square feet
8.25ft2 times 4lbmulch/1ft2 = 33lb mulch
