To find the five-number summary, we identify the minimum (63), first quartile (65), median (66), third quartile (70), and maximum (75).
For the standard deviation, we first calculate the mean, then find the squared differences from the mean, average those squared differences, and finally take the square root of that average.
The five-number summary is (63, 65, 66, 70, 75) and the standard deviation is approximately 4.87 inches.
