Working with handheld tools B. Movement C. Carrying by hand D. Handling of objects E. Operating a machine F. Other Construct a frequency distribution, including relative frequencies, and histogram for the accompanying data from 100 accidents (the percentages agree with those in the cited article):

Answer : Step 1 : Given the accompanying data from 100 accidents (the percentages agree with those in the cited article): We consider the data. A B D A A F C A C B E B A C F D B C D A A C B E B C E A B A A A B C C D F D B B A F C B A C B E E D A B C E A A F C B D D D B D C A F A A B D E A E D B C A F A C D D A A B A F D C A C B F D A E A C D Now we have to construct a frequency distribution, including relative frequencies, and histogram for the accompanying data from 100 accidents We know that. A : Working with handheld tools B : Movement C : Carrying by hand D: Handling of objects E : Operating a machine F : Other Frequency distribution : Frequency distribution is a representation, either in a graphical or tabular format, that displays the number of observations within a given interval. A frequency distribution table is...
