3. Piles are commonly used in foundations of civil worlk structures. Test piles were driven and used to measure pile strength at a selected site. The following strength data (in kips) were collected as shown in Table 2: Table 2. Pile number and strength in kips ile N Strength 8829 10236 5101 9144 7790 9327 8470 10570 10186 9305 10746 9069 11436 10044 10281 12311 0639 0215 8723 8877 20 a. Plot the histogram and frequency diagrams for pile strength b. For the data, determine the central tendency measures (average value, median, and mode). You may use the functions in Excel for the calculations, but you must show the equations. c. For the data, determine the dispersion measures: the variance, standard deviation, and coefficient of variation. You may use the functions in Excel for the calculations, but you must show the equations. d. Discuss the data with respect to the statistical tests (skewness, normally distributed, etc.)
