First we need to find the standard error. In the previous module, we met the formula for calculating the standard deviation of the distribution of sampling proportions. But we don't know the population proportion, p. So to calculate the standard deviation (a.k.a. the standard error) we estimate the standard error with the sample proportion . In this scenario we are given that that a random sample of 100 part-time college students is 68% female. So the sample proportion of females is and . Calculate the standard error. Round to three decimal places
