Answer:
The probability is;
0.0000003645
Step-by-step explanation:
The probability of packages being early p is 90% = 0.9
The probability of packages being late q will be 1-p = 1-0.9 = 0.1
So the probability of 2 out of 10 random late will be subject to Bernoulli approximation of the Binomial theorem
That will be;
P(X = 2) = 10 C 2 0.9^2 0.1^8
= 0.0000003645
Answer:
A: undercoverage bias
Step-by-step explanation:
Undercoverage bias occurs in a study or sampling when some elements of the sample population are not represented or inadequately represented.
In this case study, random sampling using phone book will not adequately represent the true size of the population since 4% have no phone, and 15% have unlisted home numbers, while only 10% have only cell phones. This sampling suffers from undercoverage bias
