The rate at which customers are served at an airport check-in counter is a Poisson process with a rate of 8.1 per hour. The prob

Answer:

Value of a is 0.667

Step-by-step explanation:

We are given the following in the question:

The rate of customer at an airport follows a Poisson distribution with

$\lambda = 8.1$

The normal approximation of Poisson distribution can be done in the following manner

$\mu = \lambda = 8.1\\\sigma^2 = \lambda = 8.1\\\sigma = \sqrt{8.1} = 2.85$

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of a such that

$P(X_p > 50)=P(Z > a)$

More than 50 customers per 5 hours means more than 10 customer per hour.

Thus, we can write

$P( x > 10) = P( z > \displaystyle\frac{10 - 8.1}{2.85}) = P(z > 0.667)$

Therefore, value of a is 0.667

Answer:

$z^{\frac{1}{3}}$

Step-by-step explanation:

$\frac{z^{-\frac{1}{3} }}{z^{-\frac{5}{6} }} \\\\=z^{-\frac{1}{3} }*z^{\frac{5}{6} }\\\\=z^{-1/3+5/6}\\\\=z^{-2/6+5/6}\\\\=z^{3/6}\\\\=z^{1/3}\\\\=z^{\frac{1}{3} }$

I believe the answer to that problem would be $68.55, since you have to add them together and then multiply them by .07 for the percentage.
