The Director of Admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall sem
VMariaS [17]

Answer:

Variance = 24900

Standard Deviation = 157.7973        

Step-by-step explanation:

We are given the following in the question:

Number of admissions:    1000     1200    1500

Admissions Probability:     0.6        0.3       0.1

Formula:

E(x) = \displaystyle\sum x_iP(x_i)\\E(x) = 1000(0.6) + 1200(0.3) + 1500(0.1)\\E(x) = 1110\\E(x^2) =  \displaystyle\sum x_i^2P(x_i)\\E(x^2) = (1000)^2(0.6) + (1200)^2(0.3) + (1500)^2(0.1)\\E(x^2) = 1257000

Variance =

\sigma^2 = E(x^2) - (E(x))^2\\\sigma^2 = 1257000 -(1110)^2\\\sigma^2 =24900

Thus, the variance is 24900.

Standard Deviation =

\sigma = \sqrt{\sigma^2} = \sqrt{24900} = 157.7973

Thus, the standard deviation is 157.7973
