Question

The minute duration of a random category of dramas in Netflix are the following: 93, 83, 76, 92, 77, 81, 78, 100, 78, and 76. • Estimate the true mean duration (in minutes) of all the dramas in Netflix. Assume that variable is normally distributed. Then, in creating interval, use 95% degree confidence. • Estimate the population (pop'n) variance and population (pop'n) standard deviation of the duration of dramas in Netflix. Assume that variable is normally distributed.

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.
