- what is z observed?arrow_forwardDetermine the mean waiting time W for an M/M/2 system when lambda = 2 and μ = 1.2. Compare this with the mean waiting time in an M/M/1 system whose arrival rate is lambda = 1 and service rate is μ = 1.2. Since the arrival rate per server is the same in both cases and service times don’t vary, should the wait times be the same in both cases?arrow_forwardA sample of 120 employees of a company is selected, and the average age is found to be 37 years.

- Suppose you are interested in the percentage of students who had burrito for lunch in your statistics class. There are a total of 120 students in your class. Instead of asking each student whether they had burrito for lunch, you randomly picked 36 students from the class and found that 11 students had burrito for lunch. Calculate a single value to estimate the parameter of interestarrow_forwardFind the first derivative of the Maxwell-Boltzmann Distribution of Molecular Speeds. Set the first derivative of the Maxwell-Boltzmann Distribution of Molecular Speeds equal to zero and solve for the most probable speed.arrow_forwardLet X and Y be independent Exp(2) random variables. Define W = X + Y. a) Determine the correlation between X and W. The joint pdf of X and W is: fx,w(x, w) = 1^(2) e^(-1w) I{Oarrow_forwardEach front tire on a particular type of vehicle is supposed to be filled to a pressure of 26 psi.

The World Health Organization measures child development by comparing the weights of children who are the same height and the same gender. In 2009, weights for all 80 cm girls in the reference population had a mean µ = 10.2 kg and standard deviation σ = 0.8 kg. Weights are approximately normally distributed. X ~ N(10.2, 0.64), where the notation N(a,b) stands for a normal distribution with mean a and variance (square of the standard deviation) b. Calculate the z-scores that correspond to the 12.2 kg.

(i) What is the probability that an aquatic insect lives longer than 12 hrs? (ii) What is the median of this distribution? (50% live less time and 50% live longer) (iii) Assume the lifetimes of these insects are independent of each other. What is the probability that at least 35 of the next 100 insects live longer than 12 hrs?arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
