Answer:
Option d (quantitative data) is the correct choice.
Step-by-step explanation:
- Quantitative data seems to be a collection or kind of data which is concerned regarding quantitative information or methods. That indicates its value, as well as the condition, could be represented arithmetically.
- All evidence that can be quantified, checked, and suitable for statistical analysis categorizes as quantitative methods.

Answer:
option (a) It will be closer to 30 than to 20
Step-by-step explanation:
Data provided in the question:
For sample 1:
n₁ = 10
variance, s₁² = 20
For sample 2:
n₂ = 15
variance, s₂² = 30
Now,
The pooled variance is calculated using the formula,

on substituting the given respective values, we get

or
= 26.0869
Hence,
the pooled variance will be closer to 30 than to 20
Therefore,
The correct answer is option (a) It will be closer to 30 than to 20
I believe its 27 cause u have to multiply 3 times 3 which is 9, then 3 times 9 which is 27
