Question
(b) 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 at least ten papers more than ten papers c) Suppose the five 15s, three 16s, and three 17s had been lumped into a single category displayed as "215." Would you be able to draw a histogram? Explain. OYes; this class does have a finite width of 3, so the relative frequency of category "215" can be plotted as a rectangle of height 0.831 No; the classes cannot be combined in such a manner because the increments would not be equivalent. No; this class has no upper boundary, so it is impossible to draw a rectangle above it having finite area (.e., frequency) (d) Suppose that instead of the values 15, 16, and 17 being listed separately, they had been combined into 15-17 category with frequency 11. Would you be able to draw a histogram? Explain O Yes; this class does have a finite width of 3, so the relative frequency of category "15-17" can be plotted as a rectangle of height 0.831 No; this class has no upper boundary, so it is impossible to draw a rectangle above it having finite area (i.e, frequency) No; the classes cannot be combined in such a manner because the increments would not be equivalentExplanation / Answer
from abvoe:
a) correct graph has been chosen
heavy positive skewness
b)
at least 5 papers =P(X>=5) =1-P(X<=4)=1-0.5889-0.1597-0.0995-0.0392=0.1128 ( please try 0.1127 if this comes wrong)
at least 10 papers = P(X>=10)=0.0305 ( please try 0.0304 if this comes wrong)
more than 10 papers =P(X>10)=0.0251 ( please try 0.0250 if this comes wrong)
c)
no the classes can not be combined in such a manner,,,,,,,,,
d)
no the classes can not be combined in such a manner,,,,,,,,,
