Question Below:

It is known that 5% of people in a city are infected by covid-19. A random sample of 100 people will be selected. What is the
probability the percentage of people in the sample who is infected is between 49% and 66?
The sample is not large enough to apply the Central Limit Theorem. A Binomial distribution should be used to compute
the probability.
The sample is not large enough to apply the Central Limit Theorem, the question can not be answered.
The sample is large enough to apply the Central Limit Theorem. A Normal distribution is used to compute the
probability.
The sample is large enough to apply the Central Limit Theorem. A binomial distribution is used to compute the
probability.
