Data from a representative sample were used to estimate that 33% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money. You decide to conduct a survey to estimate this proportion for the current year. What is the required sample size if you want to estimate this proportion with margin of error of 0.04? Calculate the required sample size first using 0.33 as a preliminary estimate of p. (Round your answer up to the nearest integer.) USE SALT Calculate the required sample size using the conservative value of 0.5. (Round your answer up to the nearest integer.) How do the two sample sizes compare? The sample size computed using the preliminary estimate is ---Select-- the sample size computed using the conservative value. What sample size would you recommend for this study? (Round your sample size up to the nearest integer.) The sample size of greater than 0.04 if p < Submit Answer should be used for this study because it will guarantee a margin of error of no greater than 0.04. The other sample size computed will only guarantee a margin of error no or if p >
