How to estimate the number of times that Greg is on time to class?
The given parameters are:
Probability that Greg is on time, p = 14%
The sample size, n = 30
The estimate of the number of times that Greg is on time to class is
E(x) = np
Substitute the known values in the above equation
E(x) = 30 * 13%
Evaluate the product
E(x) = 3.9
Approximate
E(x) = 4
Hence, the number of times that Greg is on time to class is 4
