Answer:
89.44%
Explanation:
As we know that:
Z = (Cash Flow - Mean) / Standard Deviation
Here
Cash flow is the observed value which is the lower limit here and is $11,000
Mean is the average value of the sample and is $16,000
Standard Deviation is $4,000
By putting values, we have:
Z = ($11,000 - $16,000) / $4,000
= -1.25
The Z value lower than -1.25 is 0.1056 or 10.56%
This means that the probability of cash flow lower than $11,000 is 10.56% and the probability of cash flow greater than $11,000 will be
Probability of cash flow = (1- 0.1056) = 0.8944 which is 89.44%
