We do another survey, this time using a random sample of 200 students and find that 80 students have ticked the box marked 'Science students' (120 have ticked the box marked 'not Science' students). (3) Using the second sample, what is the sample proportion of statistics students who are Science students (type the proportion, correct to 2 decimal places, into the box) Our sample size is now definitely big enough for us to assume that the sampling distribution of the sample proportion is approximately normal. (4) Using the second sample, what expression would we use to calculate a 95% confidence interval for the sample proportion of statistics students who are Science students?
