Probability mass function-poisson

Reference no: EM13103637

An article in Annals of Mathematical Statistics reports the following data on the number of borers in each of 120 groups of borers. Does the Poisson pmf provide a plausible model for the distribution of the number of borers in a group? (Hint: Add the frequencies for 7,8,..., 12 to establish a single category "> 7").

No. of Borers 0 1 2 3 4 5 6 7 8 9 10 11 12

Frequency 24 16 16 18 15 9 6 5 3 4 3 0 1
