Question

Initial class boundary of 12.5, an ending class boundary of 47.5, and 5 classes of equal width.

a) True
b) False

Answer 1

The statements are false because the data from 4-5 and 5-7 are equal, the presence of data values of three is unknown, and 50 percent of the data are four or less.

Step-by-step explanation:

B. False - there are equal amounts of data from 4-5 and from 5-7 because the classes have equal widths. C. False - it is unknown whether there are any data values of three, as the box plot in Figure A2 does not show this information. D. False - 50 percent of the data are four or less, not exactly four.
