Determine whether the random variable described is discrete or continuous. The amount of time you wait at a bus stop. The random variable described is (Choose one) discrete continuous X Ś

Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable. (a) The number of people with blood type A in a random sample of 14 people. (b) The time it takes to fly from City A to City B. (a) is the number of people with blood type A in a random sample of 14 people discrete or continuous? OA. The random variable is continuous. The possible values are 0≤x≤ 14. B. The random variable is discrete. The possible values are x = 0, 1, 2,..., 14. OC. The random variable is discrete. The possible values are 0 ≤x≤ 14. O D. The random variable is continuous. The possible values are x = 0, 1, 2,..., 14. (b) is the time it takes to fly from City A to City B discrete or continuous? .RE OA. The random variable is continuous. The possible values are t> 0. OB. The random variable is discrete. The possible values are t= 1, 2, 3, ... OC. The random variable is discrete. The possible values are t > 0. OD. The random variable is…

Random ------ helps one obtain a sample that is representative of the population whereas random assignment ensures the two groups are as equivalent as possible.

Directions: During a certain part of the day, the time between arrivals of automobiles at the tollgate on a turnpike is an exponential random variable with expected value 30 seconds. 1. Find the probability that the time between successive arrivals is more than 70 seconds. Probability = 2. Find the probability that the time between successive arrivals is greater than 10 seconds and less than 50 seconds. Probability =

Which of the following are examples of continuous random variables? Select all that apply. The percent change in the price of a share of IBM stock in a month The number of claims on a medical insurance policy on a given year The speed of a randomly selected car on a highway The number of customers that enter a particular store on a randomly selected day The time that elapses between two customer service calls

Determine whether the random variable X has a binomial distribution. If it does, state the number of trials n. If it does not, explain why not. Twenty students are randomly chosen from a math class of 70 students. Let X be the total number of student absences.
