The total service time of a multistep manufacturing operation has a gamma distribution with mean 18 minutes and standard deviati

11Alexandr11 [23.1K]

Answer:

The answer is " $\bold{r=9, \lambda=\frac{1}{2}\ and \ \ \text{exponential, 9 steps}}$ "

Step-by-step explanation:

In point a:

We are aware of the random gamma variable X:

$\to \mathbb{E} =\frac{r}{\lambda}\\\\\to Std(X) =\frac{\sqrt{r}}{\lambda}\\\\$

It is given:

$\to \mathbb{E} = 18 \\\\\to std(X)=6$

$\to 18=\frac{r}{\lambda}\\\\ \to 6=\frac{\sqrt{r}}{\lambda}\\\\$

Substituting the value:

$\to \frac{\sqrt{r}}{6}=\frac{r}{18}\\\\\to r=9\\\\\to \lambda=\frac{1}{2}\\\\$

In point b:

When building the Erlang/Gammas distribution, these could reasonably be assumed to become an exponential distribution only with \lambda = 1/2 parameter with one step but to be r = 9 for one step.

Kim drives x miles a week. Terry drives two times more than Kim and Jerry drives three times more than Terry. Which expression r

Anastasy [175]

Kim drives = x
Terry drives = 2x
Jerry drives = 6x

Let us go through our answer choices and choose one.

A is incorrect because we are not being asked to add anything.

B is incorrect because it equals what all of the drivers drive.

2(x+3)
2*x + 2*3
2x + 6x

C is incorrect because we are not being asked to subtract.

D is correct because Jerry drives 3 times as much as terry.

2x*3
6x

So our final answer is D. 6x
