There are 50 classrooms on a particular school campus. The school district wants to see if students have been adequately trained to deal with earthquakes. They want to determine the average time students get under a desk or table to "duck and cover". They randomly select 5 science labs and find the average time is 27.3 seconds for all students to get under a desk when an alarm goes off. Which of the following is NOT TRUE? The parameter is the mean amount of time it takes ALL students to get under a desk and "duck and cover". The statistic of 27.3 seconds is the mean amount of time it takes the sampled students to get under a desk and "duck and cover". The sample does not represent all students because they only included "science labs" The sample is representative of all students because they used a cluster sampling method that uses randomization.
