iii) It is assumed that 66% of the population is in support of the new Sex Education program proposed by the new Provincial Government. A large sample of 205 people were asked whether they supported it or not. (A simple question.) What is the probability of randomly recruiting a large sample of this size and getting a result greater than 70% in support of this new program? (i.e.greater than 143 people in this sample saying yes! ) (5)

In answering this question, prepare the PDF. (3)

iv) Over 3000 students have taken this course over the past 12 years. The mean (average) mark for these students is 72% and the standard deviation is 12%. Is it unusual for a student to get a mark greater than 90% (an A+) in this course? (5)

Also prepare the PDF depicting this problem. (2)
