A newspaper article claims that 44% of all airplanes arriving at Piarco Airport are late. Seven(7) flights are randomly selected.
----
(a) Define the variable of interest. [1]
Of the seven flights, how many aarrive late.
------------------------------------------------------------
(b) State clearly the appropriate distribution for this scenario. Justify your answer. [5]
Binomial Distribution with n = 7 and p(late) = 0.44
---------------------------------------------------------
(c) Find the probability at least 1 flight will arrive late. [4]
P(at least one late) = 1 - P(none late)
----
P(at least one late) = 1 - 0.56^7 = 0.9805
