Answer:
The parameters of this exponential distribution is = .
Step-by-step explanation:
We are given that the random variable X is known to be exponentially distributed and let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes.
<u><em>So, X = time it takes for a person to choose a birthday gift</em></u>
The probability distribution function of exponential distribution is given by;
where, = parameter of distribution.
Now, the mean of exponential distribution is = which is given to us as average value of 27 minutes that means .
So, X ~ Exp( ) .
Therefore, the parameter of this exponential distribution is .
Answer: Exactly One Solution
Step-by-step explanation: All you have to do is evaluate the problem.
9z - 6 + 72 = 162 - 6
9z - 6 + 72 = 156
9z + 66 = 156
9z = 90
z = 10
