Use the given data to find the minimum sample size required to estimate the population proportion. Margin of error: 0.028; confidence level: 99%; p and q unknown

The minimum sample size is

Step-by-step explanation:

From the question we are told that

    The margin of error is  

Given that the confidence level is  99% then the level of significance is evaluated as

Next we obtain the critical value of   from the normal distribution table

   The  value is  

Now let  assume that the sample proportion is  

  hence  

=>            

   Generally the sample size is mathematically represented as

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!

decreased by 33.333333334%
