Answer:

Independent-samples t-test.

Step-by-step explanation:

We are looking for the appropriate design for testing the significance of the difference between the means.

Now, there is a parametric test known as the Independent Samples t Test and what this test does is that it compares the mean of two independent groups in order to find out whether there is statistical evidence that the related population mean is significantly different.

Thus, the test to be used here is Independent-samples t-test.

Since x=-1 and y=3
ax-2y=4
a(-1)-2(3)=4
-a-6=4
-a=10
a=-10

5x+by=-1
5(-1)+b(3)=-1
-5+3b=-1
3b=4

Target Costing
Lynna [10]

The target cost for Model J20 is $2000.

The required cost reduction is $30.

The total saving will be $30.3.

<h3>How to compute the cost?</h3>

The target cost will be:

= Sales price - (100% × Target cost)

= 400 - (100% × Y)

Y + Y = 400

2Y = 400

Y = 400/2 = 200

Target cost = $200

Therefore, the target cost is $200.

The required cost reduction will be:

= $230 - $200

= $30

The required cost reduction is $30.

The three engineering improvements together will be:

Direct labor reduction = 7.5

Additional inspection = 17

Injection molding = 5.8

Total savings = 30.3

The total savings is $30.3.
