Normal Distribution

The average confirmed COVID-19 cases in the whole Philippines everyday is 1000 people with a standard deviation of 150.

1. Construct a normal distribution table and describe the data in one, two, and three standard deviations of the mean.

2. Compute the probability that there will be less than 800 COVID-19 cases in a day (in percent).

3. Compute the probability that there will be more than 1,100 COVID-19 cases in a day (in percent).

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.
