Question

The probability of success in each of the 58 identical engine tests is p = 0.92. What is the mean of this binomial distribution?

Answer 1

53.36

Explanation:

The mean of binomial distribution is calculated by multiplying number of trials to probability of success. It can be denoted as

E(x)=mean=np

Where n is the fixed number of trails and p is the probability of success.

Here, n=58 and p=0.92

E(x)=np

E(x)=58*0.92

E(x)=53.36

So, the mean of the given binomial distribution is 53.36.
