Answer:

[tex]a. Systematic \ sampling\\b. Sampling \ Frame: \ Every \ 15^t^h \ person \ on \ line \ of \ the \ roller \ coaster[/tex]

Step-by-step explanation:

a. Systematic sampling

Reason-Every [tex]k^t^h[/tex] individual will be in the sample. The [tex]every \ 15^t^h[/tex] is referred to as the sampling interval.

-The sampling interval has a random start point but with a fixed, periodic interval.

-This method was appropriate given the homogeneous nature of the population.

-It is also representative given it has no bias.

b. A sample frame is the part of a population from which information is drawn.# In our sample, the sample frame is [tex]every \ 15^t^h[/tex] person.

#No parts c, d as implied in the question
