Question

i) Assuming that the runs made by the Indian cricket team in one day matches follow
normal distribution. The following is the data on the runs made by the Indian team in ten one
day matches.
110, 150, 130, 170, 180, 100, 160, 140, 170, 130.
a) Calculate the maximum likelihood estimate of true average runs made.
b) Also calculate the maximum likelihood estimate of the true standard deviation of the
distribution.
c) Estimate the 75th percentile of the distribution.

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.
