** Question 1: Consider the following discrete probability distribution. The mean of this random variable is 3.75. x 0 1 2 5 P(X=x) 0.10 0.70 a) Find the missing values for P(X=1) and P(X=2) Hint: you will need to use two equations here, and substitution. This should be familiar from high school mathematics. The two equations you will need are for the mean of a discrete random variable and that the sum of all the probabilities equals 1. - please...
Assume the commute time is a random variable that follows the normal distribution with a mean...
Assume the commute time is a random variable that follows the normal distribution with a mean of 10.3 minutes with a standard deviation of 4.8 minutes. You wish to calculate the probability that the commute time is more than 16.3 minutes. What is the z value you would look up in the standard normal table to answer this question? What is the probability that the commute time is more than 16.3 minutes? What would be the targeted average commute time...

Part 3: The Uniform Distribution
Suppose that you need to take a bus that comes every 30 minutes.
Assume that the amount of time you have to wait for this bus has a
uniform distribution between 0 and 30 minutes. The probability
density curve for this distribution is given below.
1) Is waiting time a discrete or continuous random variable?
2) What is the area of this entire rectangle?
3) What numbers are represented by a, b and c (note:...

The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the probability of an occurrence is the same in any two time periods of an equal length. It is known that the mean number of occurrences in ten minutes is 5.4. What is the appropriate probability distribution for the random variable? a)continuous b)either discrete or continuous depending on how the interval is defined c)binomial d)discrete
