Fifty-three percent of employees make judgements about their co-workers based on the cleanliness of their desk. you randomly select 8 employees and ask them if they judge co-workers based on this criterion. the random variable is the number of employees who judge their co-workers by cleanliness. which outcomes of this binomial distribution would be considered unusual?

No employees or 8 employees judging co-workers based on the cleanliness of their desk would be considered unusual outcomes.

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

The standard deviation of the binomial distribution is:

Outcomes are unusual when they are more than 2.5 standard deviations of the mean.

In this problem, we have that:

So

No employees or 8 employees judging co-workers based on the cleanliness of their desk would be considered unusual outcomes.
