The weight of male american between the ages 18 to 25 is normally distributed, with mean of 162.7 lb and a standard deviation of 28 lb. one definition of obesity states that a person is obese if the z-score of his or her weight is greater than 2. what is the obesity threshold weight for a young adult american male? round your answer to the nearest tenth.

218.7 lb.

Step-by-step explanation:

We have been given that the  weight of male american between the ages 18 to 25 is normally distributed, with mean of 162.7 lb and a standard deviation of 28 lb.

One definition of obesity states that a person is obese if the z-score of his or her weight is greater than 2.

We will use z-score formula to solve our given problem.

, where,

,

,

,

.

Upon substituting our given values in z-score formula we will get,

Now let us solve for x.

Upon multiplying both sides of our equation by 28 we will get,

Let us add 162.7 to both sides of our equation.

Therefore, the obesity threshold weight for a young adult American male is 218.7 pounds.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
