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.

$Mean = np\\Mean = 200\times 0.139\\Mean = 27.8$

Hence, the mean is 27.8

Part (b) variance of the random variable "number of grads who are unemployed.

$Variance = np(1-p)\\Variance = 200\times 0.139(1-0.139)\\Variance = 27.8(0.861)\\Variance = 23.9358$

Hence, the required variance is 23.9358
