5, 750 students are enrolled.
As a rule of thumb, the sampling distribution of the sample proportion can be approximated by a normal probability distribution whenever the sample size is large.
<h3>What is the Central limit theorem?</h3>
- The Central limit theorem says that the normal probability distribution is used to approximate the sampling distribution of the sample proportions and sample means whenever the sample size is large.
- Approximation of the distribution occurs when the sample size is greater than or equal to 30 and n(1 - p) ≥ 5.
Thus, as a rule of thumb, the sampling distribution of the sample proportions can be approximated by a normal probability distribution when the sample size is large and each element is selected independently from the same population.

Answer:
4.8 in
Step-by-step explanation:
feet to inch conversion is *12
2 * 12 = 24
then divide the scale (for every 1 in on the model there is 5 in on the actual, so divide the actual value by 5)
24/5 = 4.8
your answer is 4.8 in
hope this helps:)
