49
Step-by-step explanation:
Given:
Width = 0.4
Let's take the z value of 95% which is = 1.96
Let's assume population proportion p1 and p2 = 0.5
For margin of error E, the relation between the width and margin of error is 2E.
i.e 2E = 0.4
E = 0.2
To find the sample size, n, let's use the formula :


= 48.02
≈ 49

1) <u>Voluntary deductions</u> are amounts that you elect to come out of your paycheck every pay period. Federal tax is not voluntary; neither is state tax, nor Social Security. The only voluntary deduction in this list is health insurance. You are not obligated to pay for your health insurance by automatically withholding it from your check.
2) <u>FICA</u> is the tax that goes towards Social Security and Medicare. It is involuntary, and it is deducted as a percentage of your gross (pre-withholding) pay.
3) <u>A fixed expense</u> would be one that is the same from month to month. The only one of these expenses that would be the same amount monthly is a mortgage.</span></span>
