Based on historical data in Oxnard college, we believe that 41% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to estimate the proportiton of freshmen who do not visit their counselors regularly. You would like to be 99% confident that your estimate is within 4.5% of the true population proportion. How large of a sample size is required? Do not round mid-calculation. n =

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.
