A research group is interested in gauging perceptions about airline food quality among first class passengers. ​Specifically, they wish to determine the percentage of business travelers In the United States that believe airline food quality has not improved. They listed the members of the airline's frequent flyer club in alphabetical order and took every tenth member until they succeeded in contacting 170 members. What kind of sampling method have they​used? a. MULTISTAGE SAMPLING

b. CLUSTER SAMPLING

c. STRATIFIED RANDOM SAMPLING

d. SYSTEMATIC SAMPLING

d. SYSTEMATIC SAMPLING

Step-by-step explanation:

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this question:

Took every 10th member, that is, every kth member, which is systematic.

The correct answer is given by option d.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
