5.14 Social network densities. Social networks involve inter-actions (connections) between members of the network.Sociologists define network density as the ratio of actualnetwork connections to the number of possible one-to-oneconnections. For example, a network with 10 members has()-C) = 45 total possible connections. If that network has||only 5 connections, the network density is 5/45 = .111.Sociologists at the University of Michigan assumed that thedensity x of a social network would follow a uniform distri-bution between 0 and 1 (Social Networks, 2010).a. On average, what is the density of a randomly selectedsocial network?b. What is the probability that the randomly selected net-work has a density higher than .7?c. Consider a social network with only 2 members. Explainwhy the uniform model would not be a good approxi-mation for the distribution of network density.

Answered: 45 total possible connections. If that…

9) Coal is carried from a mine in West Virginia to a power plant in New York in hopper cars on a long train. The automatic hopper car loader is set to put 85 tons of coal in each car. The actual weights of coal loaded into each car are normally distributed, with mean u = 85 tons and standard deviation o = 1.2 ton. a) What is the probability that a car chosen at random will have less than 83.5 tons of coal? ode Jedanocon vebol Au oloe ( g laenuoo of el dot 92orw 191ow lsiooe s al oA.21sbnatto emod ton asob nooeg s ansem 2200ue b) What is the probability that 20 cars chosen at random will have a mean load weight i of less dedotg sni bni ts noale lle to 08 ng A nevig need 2ed opilA abnatto isegsi than 83.5 tons of coal? quo1g eaollA ai aeelonsq to 1edmun babsgke arb ai terlW (d Snoiteivsb bisbnale e sW Sansbnotto 10) Suppose x has a normal distribution with o = 6.

A candle factory produces candles that are marketed as 15 cm long. There is some variability in the length of the candles manufactured - candle length has a continuous uniform distribution between 145 mm and 154 mm. These candles are sold in packages of 20. What is the probability that a random package will contain more than 5 candles which are over 150 mm in length. (Hint: First compute the probability that any single candle will be over 150 mm in length).*

Suppose that the flight time from Chicago O'Hare International Airport to Hartsfield- Jackson Atlanta International Airport follows a uniform distribution with lower and upper bounds of 120 and 140 minutes, respectively. a) Suppose that Luke flies with Spirit Airlines, which posts a flight time of 2 hours and 5 minutes (that is, 125 minutes) for this route. What is the chance that his flight will be at most 5 minutes late? Hint: what is P(X < 130)? b) Let the flight duration be a random variable. Find the expected value and standard deviation of this variable.
