Question

For the flow dataset (42-years of annual flow values) described earlier:

(a) fit the normal distribution to this data set on a normal probability paper and show computations in a tabular form,

(b) fit the log-normal distribution to this data set on a log-normal probability paper and show computations in a tabular form,

(c) for both of the fitted distributions, compute the 90% confidence limits for the fitted probability curves and also show computations in a tabular form.
In each case as listed above predict the 100-year, 150-year, and 200-year floods and compare results and how comparable are these results?

please solve this question becuase i am struggling a lot

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.
