Hello!
Stratified sampling involves the categorization of the population into subgroups based on pre-established criteria for the study. These subgroups consist of homogeneous units concerning the relevant characteristics. In this instance, individuals in the groups will represent only one of the two potential opinions (support or not support) and not both.
The researcher determines the sample size desired, considering several factors such as finances, material availability, and accessibility to experimental subjects (for instance, if they are endangered species, larger sample sizes may not be feasible).
One might conduct proportionate stratified sampling by selecting a proportion of respondents who answered "yes" along with those who answered "no."
In this sampling method, taking a specific proportion from each subgroup allows for a more straightforward extrapolation of results to the overall populations. For example, if you needed a sample size of n = 20, each stratum would ideally contain half, meaning 10 from the “yes” group and 10 from the “no” group.
I hope this is helpful!

Answer:
The distance he covered is 17.69.
Step-by-step explanation:
Simply multiply 12.2 by 1.45. This calculation yields a total distance of 17.69.
No, mixed numbers must include both a whole number and a fraction to qualify as such. If a fraction were present, it wouldn’t sum to two due to the presence of the 1's ❤️.
Response:
Tan x = 125/500 = 0.25
therefore, x = arctan (0.25)
= 14 degrees
