Answer:
The confidence interval is between 2.23 and 3.53
Explanation:
The confidence interval (C) = 99% = 0.99
α = 1 - C = 1 - 0.99 = 0.01
α/2 = 0.01/2 = 0.005
The z score of α/2 corresponds to the z score of 0.495 (0.5 - 0.005) which is 2.576
The margin of error (E) is given as:

The confidence interval = mean ± margin of error = 2.88 ± 0.65 = (2.23, 3.53)
The confidence interval is between 2.23 and 3.53

One way of representing attaining the positive externality by the government is through the promotion of education.
Option D is the correct answer.
<h3>What is an externality?</h3>
When the cost or advantage is received by a third party that is not related to the economic activity, then it is considered an externality.
A positive externality is the arousal of a positive effect on either production or consumption. The act of penalizing a company for pollution, imposing taxes on citizens earning more than $250,000 and the reduction in rates of interest would all be classified as negative externalities.
Therefore, the encouragement of education by the government is regarded as a positive externality.
