The Education Minister of a province would like to know if there is a difference whether international students choose university over college when applying for post-secondary schools in his province. A simple random sample of 200 students are selected from the University and in that sample there are 35 international students. A simple random sample of 80 students are selected from the College, and in that sample, there are 28 international students. The standard error for a 9% confidence interval for the true mean difference in proportion of international students from both schools is. O (0. 175 0.825) 200 + 80 O (0.350) (0.650 ) 1 200 + 80 O 0.175(0.825) 0.350(0.650) + 80 200 0.175(0.825) 0.350(0.050 + 200 80 (0. 225) (0. 775) 200 + 80
