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.

Describe the relationship between the two quantities. amount of money earned; number of hours worked a. inverse c. joint b. dire
tatyana61 [14]

The relationship between the two quantities that is the amount of money earned and number of hours worked is direct .

The correct option is B

When two values x and y can be represented in the general form y = kx, where k is the proportionality constant, then there is a proportional relationship between them.

In the equation y= kx, the amount of money a person makes is directly related to the amount of time they work.

FOR EXAMPLE -

Since a person earns $100 for 5 hours of work, we can use this information to find the value of  k. Substituting 100 and 5 into the equation results in 100 = k 5.  Solving for k produces  k = 20.  Now we can write a specific equation relating the money earned and the hours worked as  y = 20x.

y= 20(18) = $360
