Answer:
Minimum number of truck drivers that the statistician should sample in these southern states in order to achieve the desired accuracy is 1309.
Step-by-step explanation:
Consider the provided information.
The estimate accurate to within 3%
Therefore, e = 0.03
The true proportion with 97% confidence.
For 97% CI critical Z = 2.1701
p = 1/2 = 0.5
We can calculate the sample size by using the formula.
Substitute the respective values
Hence, minimum number of truck drivers that the statistician should sample in these southern states in order to achieve the desired accuracy is 1309.
