Answer:
I guess is
Step-by-step explanation:
False I guess
Match the data to the summary 5,10,15,20,25,25,25,30,35,40,45,50
Serjik [45]
Minimum = 5
maximum = 50
Q1 = (15 + 20)/2 = 17.5
Q2 (median) is 25
Q3 = (35 + 40)/2 = 37.5
If i were going by guesses i’d say y=x. sorry if i’m wrong.
Answer:
The shape and rate parameters are
and
.
Step-by-step explanation:
Let <em>X</em> = service time for each individual.
The average service time is, <em>β</em> = 12 minutes.
The random variable follows an Exponential distribution with parameter,
.
The service time for the next 3 customers is,
<em>Z</em> = <em>X</em>₁ + <em>X</em>₂ + <em>X</em>₃
All the <em>X</em>
's are independent Exponential random variable.
The sum of independent Exponential random variables is known as a Gamma or Erlang random variable.
The random variable <em>Z</em> follows a Gamma distribution with parameters (<em>α</em>, <em>n</em>).
The parameters are:

Thus, the shape and rate parameters are
and
.
