At a cell phone assembly plant, 84% of the cell phone keypads pass inspection. A random sample of 106 keypads is analyzed. Find the mean $\underset { p } { \mu ^ { \wedge } }$
A) 0.16
B) 0.96
C) 0.036
D) 0.84

Question

Quizplus · Accepted Answer

The mean of a binomial distribution is given by
$\mu=p$
where $p$ is the probability of success. 
In this case, the probability of a keypad passing inspection is 0.84. Therefore, the mean is $\mu=0.84$.
