Question

A study is being done by a group of pediatricians to determine the proportion that their patients experience physical symptoms of COVID-19 within 2 weeks after contracting the disease. A sample of 300 patients showed that 186 experienced physical symptoms within 2 weeks. Construct the 95% confidence interval for the true proportion of patients who experience COVID-19 symptoms within two weeks of contracting the disease.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
