Question

The depth to which a pile can be driven without hitting the rock stratum is denoted as H (see
figure below). For a certain construction site, suppose that this depth has a log-normal
distribution with mean of 30 ft and coefficient of variation of 20%. In order to provide
satisfactory support, a pile should be embedded 1 ft into the rock stratum. What is the
probability that a pile of length 40 ft will not anchor satisfactorily into the rock?

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.
