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".

Answer:
they are both going in the same dirrection but this does not mean they are parrallel or perpendicular.
Step-by-step explanation:
So just say neither
Rate of Change:
At 1 mile in 30 seconds.
At 5 miles in 2.5 minutes. 2.5 minutes = 2.5*60 = 150 seconds.
Rate of change = Change in height / Change in time
= (h₂-h₁)/(t₂-t₁)
= (5 -1) /(150 -30) = 4/120 = (1/30) = 0.0333 miles per second.
= (1/30) miles per second or 0.0333 miles per second.
To have the answer in miles per minute.
(1/30) miles per second = (1/30) miles/second.
60 seconds = 1minute
1 second = (1/60) minute.
(1/30) miles/second = (1/30) miles/(1/60)minute
= (1/30) *60 miles / minute
= 2 miles per minute.
Answer:
Data set B has less variability then Data Set A because the range of B is 29 and the range of A is 30.
Step-by-step explanation:
The range of Set A is 44-14 = 30 and the range of B is 38-9 = 29.
Answer:
The answer is 5
Step-by-step explanation:
4 times 2=8 then 8 minus 3 = 5
Therefore 5
