Answer:
1509
Step-by-step explanation:
We know that, formula for number of samples is,
When nothing is given, we take and we know that .
SE = 0.03 (the true proportion should remain withing 3%)
Putting the values we get,
Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.
Yes, it is.
Formula X+1=3/4y is linear.
No just use pythagorean theorem. a2+b2+c2
53.69*.15= 8.05
Change the 15% to a decimal before multiplying. Round answer to two decimal places since it is money (unless told otherwise)
