The probability that he can fit through the doorway without bending is 14.92%

<h3>How to find the p-value probability?</h3>

We are given;

Mean; μ = 69.5

Standard deviation; σ = 2.4

Sample mean; x' = 72

The standardized score is the value x decreased by the mean and then divided by the standard deviation. Thus;

z = (x' − μ)/σ

​z = (72 − 69.5)/2.4

​z = 1.04

Using p-value from z-score calculator gives us;

p-value = 0.1492 = 14.92%

Thus, the probability that he can fit through the doorway without bending is 14.92%

Complete Question is;

The Boeing 757-200 ER airliner carries 200 passengers and has doors with a height of 72 in. Heights of men are normally distributed with a mean of 69.5 in. and a standard deviation of 2.4 in. If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending.

scoundrel [369]

Answer:  Angle formed with height and hypotenuse is 40 degrees

Explanation:

Hi, to answer this question we have to analyze the information given:

Since the triangle is a right triangle it has a right angle that has a value 90 degrees.

Since the sum of the interior angles is equal to 180 degrees:

180 = x +50 + 90

Solving for x:

180-90-50 =x

40° =x

A political candidate has asked his/her assistant to conduct a poll to determine the percentage of people in the community that
Alexxandr [17]

Answer:

The size of the sample needed = 67.65

Explanation:

Given that :

The margin of error = 10% = 0.10

The confidence level = 90% = 0.90

Level of significance = 1 - 0.90 = 0.10

At ∝ = 0.10

Z_{\alpha/2}= Z_{0.10/2} = 1.645

Since the proportion of people that supported him/her is not given, we assumed p = 0.50

The margin of error formula can be expressed as:

M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{p(1-p)}{n}}

0.10 = 1.645 \times \sqrt{{\dfrac{0.5(1-0.5)}{n}

Squaring both sides; we have:

0.10^2 = 1.645^2 \times {\dfrac{0.5(1-0.5)}{n}

0.01 = 2.706025 \times \dfrac{0.25}{n}

n= 2.706025 \times \dfrac{0.25}{0.01 }

n = 67.65

Therefore, the required sample size = 67.65

Bagaimana cara mengubah bahasa pada aplikasi brainly...,,?

<span>I believe that there isn't a Brainly language preference. There are Spanish categories that you can get help/ answers from. I personally can not help you with Spanish questions, though this one is a bit strange. I have looked through the guide lines and didn't see anything about language preferences. Just using the Spanish category is your best bet, my friend. By the way, the Spanish translator is filtered, so i did not do that. Best of luck! :)



Creo que no es una preferencia de idioma Brainly. Hay categorías españolas que usted puede obtener ayuda / respuestas de. Yo personalmente no te puedo ayudar con preguntas de español, aunque es un poco extraño. He mirado a través de las líneas de guía y no ver nada acerca de preferencias de idioma. Utilizando la categoría española es su mejor apuesta, mi amigo. Por cierto, el traductor español es filtrado, por lo que no hago eso. ¡Mucha suerte! :)</span>
