(a) Identify the target population.
(b) Suggest and justify an appropriate sampling technique
(c) Suggest and justify an appropriate sample size.
a)
The Acai berry palms is a species of the palm tree.
The target population here will be all the Acai berry palms within Guyana.
b)
Here, systematic sampling can be used. It is a technique in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval.
This can be executed within the Guyana.
c)
The sample size can be anything around 150. 150 samples will be appropriate to conclude some useful points about the Acia berry palms.
GFC wishes to carry out a survey to characterize Acai berry palms within Guyana. (a) Identify...
