Let X = the time between two successive arrivals at the drive-up window of a local bank. If X has an exponential distribution wi
LuckyWell [14K]

Answer:

a) E(X)=1

b) σ=1

c) P(X>1)=0.368

d) P(2<X<5)=0.128

Step-by-step explanation:

We have X: "the time between two successive arrivals at the drive-up window of a local bank", exponentially distributed with λ = 1.

a) We have to compute the expected time between two successive arrivals.

The expected value for X as it is exponentially distributed is:

E(X)=\dfrac{1}{\lambda}=\dfrac{1}{1}=1

b) We have to compute the standard deviation of X.

The standard deviation is calculated as:

\sigma=\dfrac{1}{\lambda}=\dfrac{1}{1}=1

c) The probability that X is larger than 1 (P(X>1))

We can express the probability as:

P(X>t)=e^{-\lambda t}\\\\P(X>1)=e^{-\lambda\cdot 1}=e^{-1}=0.368

d) The probability that X is between 2 and 5 (P(2<X<5))

P(X>t)=e^{-\lambda t}\\\\\\P(25)\\\\P(2

Step-by-step explanation:

-4.2n-1.7=2.08 ( move the constant to the right)

-4.2n = 2.08 + 1.7( calculate)
