Kitty [74]

Answer:

70th percentile for the amount of time between customers entering is 30.10

Step-by-step explanation:

given data

mean = 25

to find out

What is the 70th percentile for the amount of time between customers entering Clay's store

solution

we know that here mean is

mean = $\frac{1}{\lambda}$ ..................1

so here 25 = $\frac{1}{\lambda}$

and we consider time value corresponding to 70th percentile = x

so we can say

P(X < x) = 1 - $e^{- \lambda *x}$

P(X < x) = 70 %

1 - $e^{\frac{-x}{25}}$ = 70 %

1 - $e^{\frac{-x}{25} }$ = 0.70

$e^{\frac{- x}{25} }$ = 0.30

take ln both side

$\frac{-x}{25}$ = ln 0.30

$\frac{x}{25}$ = 1.203973

x = 30.10

70th percentile for the amount of time between customers entering is 30.10
