Question

According to a recent report, 68% of the population has a certain medical condition. In a random sample of n=130 from this population, what is the probability at least 62.5% of the sample will have the medical conditions.

 

P(p̂ ≥ 0.625) = _________________

use normal approximation

Note: The population is very large, and a sample of n=130 represents far less than 0.01% of the entire population.

Expert Solution
Step 1

Provided data is, according to a recent report, 68% of the population has a certain medical condition. In a random sample of n=130 from this population.

For normal approximation;

μ=p=0.68σ=p1-pn=0.681-0.68130=0.0409
