Employees from Company A and Company B both receive annual bonuses. What information would you need to test the claim that the d
Natalija [7]

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

Find the surface are of this figure
Dmitriy789 [7]

Answer:

If I am correct, I think the surface area is 448.

Step-by-step explanation:

First start by finding the area of all the sides

Front side. 12 x 10 = 120

2 triangle sides: 8 x 10 = 80, 80 x 2 = 160

Bottom side: 6 x 12 = 72

Back side: 8 x 12 = 96

Then add up the surface area

120 + 160 + 72 + 96 = 448

Btw I don't know if I am correct, but I think this is the way you find surface area.

If you do 39.80/ 3 it would give you 13.2667miles and since the tip was not added that’s when you don’t do anything with that number and 3 because every mile you pay 3$
