∛216

216 = 6 * 6 * 6

∛216 = ∛(6 * 6 * 6) = 6,

Cube root of 216 = 6

Airplanes arrive at a regional airport approximately once every 15 minutes. If the probability of arrivals is exponentially dist

VARVARA [1.3K]

The answer is 0.2835

Given: Airplane arrives once every 15 minutes,

So Expected duration (µ) = 15

The rate parameter (λ) = 1/µ = 1/15

What is the expected duration (µ)?

Expected duration is the duration between two events to occur.

What is the rate parameter in exponential distribution?

The rate parameter shows how quickly the decay of the exponential function occurs. It is given by the reciprocal of expected duration that is λ = 1/µ,

where λ is the rate parameter and µ is the expected duration.

Also given that the probability of arrivals is exponentially distributed.

How to find the probability for some value (x) less than for some Random variable (X) that is distributed exponentially?

The probability for some value (x) less than for some Random variable (X) is given by

P(X<x) = 1- e^(-λx),

where

X = Random variable

x = value of some given specified condition

λ = rate parameter.

In the question, "a plane arrives in less than 5 minutes" so x = 5.

Therefore,

P(X<5) = 1 - e^(-1/15.5)

= 1 – 0.716531

= 0.283469 ≈ 0.2835.

Hence, the probability that a plane arrives in less than 5 minutes is 0.2835

The mean age of teachers at Davis senior high school is 43.6 years. If a hypothesis test is performed, how should you interpret

Ksju [112]

Answer:

The interpretation is

There is not sufficient evidence to support the claim that $\mu = 43.6$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 43.6 \ years$

Generally

The null hypothesis is $H_o : \mu = 43.6$

Given from the question that the null hypothesis was rejected then the conclusion will be

There is not sufficient evidence to support the claim that $\mu = 43.6$

$17.49 because you multiply 22 by .25 getting 5.5. You subtract that from the original 22 getting 16.5 which you then multiply by the sales tax .06. Add the tax amount to the 16.5 to get 17.49.

Answer:

The confidence interval is $64.86$

Step-by-step explanation:

From the question we are given the following data

The following heights are

66, 65, 67, 62, 62, 65, 61, 70, 66, 66, 71, 63, 69, 65, 71, 66, 66, 69, 68, 62, 65, 67, 65, 71, 65, 70, 62, 62, 63, 64, 67, 67

The sample size is n =32

The confidence level is $k = 95$ % = 0.95

The mean is evaluated as

$\= x = 66+ 65+ 67+ 62+ 62+ 65+ 61+ 70+ 66+ 66+ 71+63+ 69+ 65+ 71+ 66+ 66+ 69+ 68+ 62+ 65+ 67,+\\65+ 71+ 65+ 70+ 62+ 62+ 63+ 64+ 67+ 67 / 32$

=> $\= x = \frac{2108}{32}$

=> $\= x = 65.875$

The standard deviation is evaluated as

$\sigma = \sqrt{ v}$

Now

$v = ( 66-65.875 )^2+(65-65.875)^2+( 67-65.875)^2+ (62-65.875)^2+ (62-65.875)^2+ (65-65.875)^2+( 61-65.875)^2+ (70-65.875)^2+ (66-65.875)^2+ (66-65.875)^2+ (71+63-65.875)^2+ (69-65.875)^2+ (65-65.875)^2+ (71-65.875)^2+( 66-65.875)^2+ (66-65.875)^2+ (69-65.875)^2+ (68-65.875)^2+ (62-65.875)^2+ (65-65.875)^2+ (67-65.875)^2,+\\(65-65.875)^2+ (71-65.875)^2+ (65-65.875)^2+ (70-65.875)^2+( 62-65.875)^2+( 62-65.875)^2+ (63-65.875)^2+ (64-65.875)^2+ (67-65.875)^2+ (67-65.875)^2 / 32$
