An oil company is interested in estimating the true proportion of female truck drivers based in five southern states. a statistician hired by the oil company must determine the sample size needed in order to make the estimate accurate to within 3% of the true proportion with 97% confidence. what is the minimum number of truck drivers that the statistician should sample in these southern states in order to achieve the desired accuracy?

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.
