Answer:
represent the sample for the sample 1
represent the sample for the sample 2
represent the deviation for the sample 1
represent the deviation for the sample 2
represent the sample size for the group 1
represent the sample size for the group 2
And on this case if we create the system of hypothesis we have this:
Null hypothesis :
Alternative hypothesis:
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".
On this caseHe wants to prove that Raymondville residents (population 1) dine out more often than Rosenberg residents (population 2). So this statement need to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.
Solution to the problem
We assume that we have the following statistics:
represent the sample for the sample 1
represent the sample for the sample 2
represent the deviation for the sample 1
represent the deviation for the sample 2
represent the sample size for the group 1
represent the sample size for the group 2
And on this case if we create the system of hypothesis we have this:
Null hypothesis :
Alternative hypothesis:
Answer: Second option.
Step-by-step explanation:
Given the functions f(x) and g(x):
You need to divide them in order to find asked in the exercise. Then:
Now, it is important to remember that, by definition, the division by zero is not defined. Therefore, the denominator of the function cannot be zero.
Let's find the value of "x" for which the denominator of the function would be zero:
1. You need to make the denominator equal to zero:
2. Finally, you must solve for "x":
Therefore, as you can see, the answer is:
,
