Question
In a study of author productivity, a large number of authors were classified according to the number of articles they had published during a certain period. The results were presented in the accompanying frequency distribution: Number of papers 1 2 3 4 5 6 7 89 10 11 12 13 14 1 16 17 Frequency 800 204 127 50 33 28 19 6 7 6 7 4 4 5 3 3 Construct a histogram corresponding to this frequency distribution. What is the most interesting feature of the shape of the distribution? heavy positive skewness bimodal heavy negative skewness slight negative skewness slight positive skewness normally distributed What proportion of these authors published at least five papers? At least ten papers? More than ten papers (Round your answers to four decimal places. at least five papers 0.41715 at least ten papers__________ more than ten papers ________________Explanation / Answer
a0 option C is correct
heavy +ve skewed
b)total number of people =800+204+127+50+33+28+19+19+6+7+6+7+4+4+5+3+3=1325
number of people published at least 5 papers =33+28+19+19+6+7+6+7+4+4+5+3+3=144
hence proportion at least 5 papers =144/1325=0.1087
proportion at least 10 papers=39/1325=0.0294
more then 10 papers =32/1325=0.0241
