jok3333 [9.3K]

Answer:

a: 1037 is the minimum sample size needed

b: 712 is the minimum sample size needed

Step-by-step explanation:

We need to use the formula for minimum sample size of a proportion when a sample proportion is known.  

The level of confidence is 99%, which has a corresponding z-value of 2.575.

We know the desired error is 4%, or 0.04.  

Part a:  We have no prior estimate.  See attached photo for calculation

Part b:

We know p-hat = 0.22.  Therefore q-hat = 1 - 0.22 = 0.78

See the attached photo for the calculation of the minimum sample size
