Answer:
72 students
Step-by-step explanation:
The mean (rounded to the nearest tenth if needed) of the following data set is: 30, 29, 40, 51, 39, 33, 24, 60, 40, 35, 58

Mean is just the average so to calculate the average just add up all the data and divide it by the number of data.
so it's gonna be
(30+29+40+51+39+33+24+60+40+35+58) / 11
= 39.9 (corrected to the nearest tenth)
Answer:
Cluster Sampling
Step-by-step explanation:
I cant be 100% sure as i am not in statistics, but by definition cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research (in this case its the phone book). Researchers then select random groups (three random pages) with a simple random or systematic random sampling technique for data collection and data analysis(interviews).
so that appears to be what is happening in this scenario.
Composite, as there are multiple factors of 36.
(1,2,3,4,6,9,12,18 and 36)
