8) Section 9. 4 Exercise 18 - 19Suppose you want to estimate the proportion of traditional college students on your campus who own their own car from research on other colege campuses , youbelieve the proportion will be near 15% . What sample size is needed if you wish to be 90% confident that your estimate is within OOZ of the true proportion ?!A Sample size of 863 is neededRound up to the nearest whole number . )XThe formula for the margin of error is given below , where z* is a critical value from*the Standard Normal model corresponding to the specified confidence level , p isthe sample proportion , 9 = 1 - p . and " is the sample sizeAnME = 2*^UOK`
