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

The next four batters on a baseball team have hitting percentages of 0.400, 0.325, 0.250, and 0.300, respectively. The team curr

Travka [436]

In order to the fourth player has the opportunity to bat, he/she needs that the three previous players make hit.

The joint probability of all three first batters make a hit is the product of their hitting percentages:

0.400 * 0.325 * 0.25

Pass the decimal numbers to fractions:

4/ 10 * 325/1000 * 25/100 = 32,500 / 1,000,000

Now simplify the fraction (divide numerator and denominator by 2500):

32,500 / 2,500 = 13

1,000,000 / 2,500 = 400

Then, 32,500 / 1,000,000 = 13 / 400

Answer: 13 / 400
