Answer:
(a) The probability of waiting less than 12 minutes between successive speeders using the cumulative distribution function is 0.7981.
(b) The probability of waiting less than 12 minutes between successive speeders using the probability density function is 0.7981.
Step-by-step explanation:
The cumulative distribution function of the random variable <em>X, </em>the waiting time, in hours, between successive speeders spotted by a radar unit is:
(a)
Compute the probability of waiting less than 12 minutes between successive speeders using the cumulative distribution function as follows:
The probability is:
Thus, the probability of waiting less than 12 minutes between successive speeders using the cumulative distribution function is 0.7981.
(b)
The probability density function of <em>X</em> is:
Compute the probability of waiting less than 12 minutes between successive speeders using the probability density function as follows:
Thus, the probability of waiting less than 12 minutes between successive speeders using the probability density function is 0.7981.
