Complete question is;
Determine whether the random variable is discrete or continuous.
a. The time it takes to fly from City Upper A to City Upper B.
b. The time it takes for a light bulb to burn out.
c. The number of fish caught during a fishing tournament.
d. The number of textbook authors now sitting at a computer.
e. The distance a baseball travels in the air after being hit.
a. Is the time it takes to fly from City Upper A to City Upper B discrete or continuous? A. The random variable is discrete. B. The random variable is continuous.
Answer:
a) continuous random variable.
b) continuous random variable
c) discrete random variable
d) discrete random variable
e) continuous random variable
Step-by-step explanation:
A discrete variable is one where the value of the variable is gotten by counting the variables.
Meanwhile, a continuous variable is one where the value of the variable is gotten by measuring the variables.
For options a & b, the time taken is the variable that is measured. Thus, they are both continuous random variable.
Also, for option e, the distance traveled is the measured variable and thus it is also a continuous random variable.
In option c, the number of fishes can be counted. Also, for option d, the number of textbook authors can be counted. Thus, the values of the variables can be gotten by counting. . Therefore, they are both discrete random variable.
