Answer:
0.00000046997
Explanation:
→ Set up normal distribution without sample size
x ∼ N ( 12 , 84² )
→ Set up normal distribution with sample size
→ State probability to find
p ( 80.54 < x < 88.9 )
→ Use calculator to find the values
Lower = 80.54, Upper = 88.9, σ = √84² ÷ 36 and μ = 12
The main problem associated with using these results to draw conclusions about the general public's perception is a lack of random selection.
<h3>What is a simple random sample?</h3>
A simple random sample simply refers to a subset of items that are typically selected from a statistical population (larger data set), wherein, each member of the subset has an equal probability of being selected.
Based on this survey by the Canadian magazine, we can infer and logically deduce that the main problem associated with using the aforementioned results to draw conclusions about the general public's perception is a lack of random selection.
