Answer:
a) cluster sampling
Step-by-step explanation:
In cluster sampling method, each member of a population is assigned to one and only one group.This means clusters are formed through probability method usually a simple random sampling.The participants in the clusters are the only one to be surveyed.
In this example, simple random sampling is used to identify 12 home rooms(cluster) where a group of 20 students (participants) in each room is given the survey.
The length of the trail is 98.5 KM, all you need to do is divide the total distance by the number of times she went on it.
Answer:
D.18
Step-by-step explanation:
6-x=-12
-x=-12-6
-x=-18 divide both sides by -1
x=18
Answer: a) The probability is approximately = 0.5793
b) The probability is approximately=0.8810
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
a) The formula for z -score :
Sample size = 1
For x= 63 in. ,
The p-value = 
Thus, the probability is approximately = 0.5793
b) Sample size = 35
For x= 63 ,
The p-value = 
Thus , the probability is approximately=0.8810.
