Answer: 0.0625
Step-by-step explanation:
The answer is C. Systemic random sampling.
By definition, systemic random sampling is a sampling technique where the respondents are selected according to a <em>random starting point </em>(this alone shows that the answer is C.) The researcher then chooses the sample interval, which is the difference between two consecutive numbers in the progression.
In this case, the starting point is 8 and the sample interval is 10.
The answer is C.

Answer:
Step-by-step explanation:
We have to find out which two events are disjoint.
Two events are disjoint if both cannot happen simultaneously or Probability of both occurring is strictly 0.
a) Choose a student at random from a statistics class. Event A is that the student is a junior. Event B is that the student is a senior.
These are disjoint because a student cannot be a senior and junior both.
b) Choose a student at random from a statistics class. Event A is that the student is a psychology major. Event B is that the student is a statistics major.
Disjoint because same student cannot have psychology as well as statistics as major
c. Choose a student at random from a statistics class. Event A is that the student is at least 5'8" tall. Event B is that the student weighs at least 160 pounds.
These cannot be disjoint because there are chances for some students to be taller than 5 feet 8 inches and also having weight more than 160 lbs.
