Answer:
The mean is 27.8
The required variance is 23.9358
Step-by-step explanation:
Consider the provided information.
Here the random sample size, n = 200
Unemployment rate is 13.9% = p = 0.139
Part (a) expected number of grads who are unemployed.
Hence, the mean is 27.8
Part (b) variance of the random variable "number of grads who are unemployed.
Hence, the required variance is 23.9358
