Answer:
The correct answer is b) x - y + 1 = 0
Step-by-step explanation:
In order to find this, start by finding the slope using the two points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - 2)/(4 - 1)
m = 3/3
m = 1
Now that we have the slope, we can plug into point slope form along with either point. Then we can solve for 0 to see which equation is correct.
y - y1 = m(x - x1)
y - 2 = 1(x - 1)
y - 2 = x - 1
-x + y - 2 = -1
-x + y - 1 = 0
x - y + 1 = 0
Answer:
Step-by-step explanation:
This is a test of the mean difference between 2 independent groups or populations.
Let μ1 be the mean annual bonus of Company A's employees and μ2 be the mean annual bonus of Company B's employees.
The random variable is μ1 - μ2 = difference in the mean annual bonus of Company A's employees and the mean annual bonus of Company B's employees
We would set up the hypothesis.
The null hypothesis is
H0 : μ1 ≤ μ2 H0 : μ1 - μ2 ≤ 100
The alternative hypothesis is
H1 : μ1 > μ2 H1 : μ1 - μ2 > 100
This is a right tailed test because of the inequality sign at the alternative hypothesis. We need to take samples of annual bonuses from both company's employees and find the averages. Then we would determine the test statistic as well as the p value. We would use the p value with the level of significance to make decisions
