which of the following criteria are necessary conditions for making a statistical inference? sample size greater than 30, or an approximately normal data set sample size greater than 100 convenience sample simple random sample systematic sample
Answer
# Answer:
Sample size greater than 30, or an approximately normal data set
# Explanation:
## Step1: Recall statistical inference conditions
For many statistical inference procedures like confidence - intervals and hypothesis - tests for means, a sample size of \(n>30\) (Central Limit Theorem) or an approximately normal population (data set) is often required.
## Step2: Analyze sample size > 100
A sample size greater than 100 implies \(n > 30\), so it is part of the general condition of large sample size (\(n>30\)).
## Step3: Analyze sampling methods
Simple random sample, systematic sample, and convenience sample are sampling techniques and not criteria for statistical inference. They are about how the sample is selected, not about the conditions for making statistical inferences.
