5) In a frequency distribution, the class width is the distance between the lower and upper limits of class: (True/False). 6) Class boundaries ensure that consecutive bars of a histogram touch. (True/False). 7) The difference between the lower limits or upper limits of two consecutive classes of a frequency distribution is the Class Width. (True/False). 8) Stem-and-leaf plot: Retain the original; the stems are the last significant digit in each data value and the leaves are the remaining digits. (True/False) 9) The classes in a frequency distribution should have same width. (True/False). 10) When constructing a stem-and-leaf plot, every observation must be split into a stem and a leaf in the same way. (True/False)
