The total observations are to be determined to estimate the proportion of time spent by sergeant N in doing paperwork. Concept Introduction: Sample distribution is a process of drawing samples from the population to obtain the probability distribution of given statistics. It shows the result of statistics of every possible sample taken from a specific population.

Answer 1

Question

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.
