Out of 150 ST130 students in 2010, 52% passed. A sample of 30 randomly selected ST130 students resulted in 65% passed.
i. Describe the population and sample.
ii. Identify the parameter and give its value.
i. The population in this scenario refers to all the ST130 students in 2010, which consists of 150 students. The sample, on the other hand, is a subset of the population and consists of 30 randomly selected ST130 students.
ii. The parameter in this scenario is the proportion of ST130 students who passed. In the population, the proportion of students who passed is 52% or 0.52 (52/100). However, in the sample of 30 students, the proportion who passed is 65% or 0.65 (65/100).
