"Take a simple random sample without replacement of size 100 and estimate the proportion of respondents who think that ASA should develop some form of certification (YES=1)." In this case what formula should you use to compute this? (number of respondents in the entire population who think that ASA should develop/population size) or something else?

Homework Answers

Answer #1

Solution:

    Given:

   Take a simple random sample without replacement of size 100 and estimate the proportion of respondents who think that ASA should develop some form of certification (YES=1).

   We have to state which formula should be used to compute the proportion of respondents who think that ASA should develop.

To estimate the proportion of respondents who think that ASA should develop we use sample information, that is:Total number of respondents in the sample = n and x = number of respondents who think that ASA should develop.

Thus sample proportion is given by :

A random sample size of 100 is to be taken from a population that has a proportion equal to 0.35. The sample proportion will be used to estimate the population proportion. Calculate the probability that the sample proportion will be within ±0.05 of the population proportion. Illustrate the situation graphically, show the calculations, and explain your results in a sentence.
