a laboratory developing a new testing procedure runs the test on 1,000 patients. later confirmation shows that the experimental procedure produced remarkably few false-negative results but many false-positive results. which of the following statements is true regarding the experimental procedure?

Answers

Answer 1

It has high sensitivity, which is the true statement regarding the experimental procedure.

An example of a false positive is when a scientist concludes something is true when it is actually untrue (also called a type I error). A false alarm refers to a false positive. A false negative is when something is characterized as true when it is truly untrue (also called a type II error).

A false positive test result is one where a person's health status is reported to be indicative of an illness or condition they do not really have. An outcome when the model predicts the positive class inaccurately is known as a false positive. A false negative is a result that the model mispredicted as belonging to the negative class.

Answer 2

It has a high sensitivity level, which accurately describes the experimental technique.

A false positive is when a scientist draws the incorrect conclusion that something is true (also called a type I error). A false positive is referred to as a false alarm. When something is characterised as true when it is in fact wrong, it is termed a false negative (also called a type II error).

When a person's health state is reported to be suggestive of a disease or condition they do not actually have, it is known as a false positive test result. False positives are results where the model incorrectly predicts the positive class. A false negative is an outcome that the model incorrectly identified as being under the negative category.

TRUE/FALSE. Assault occurs when a person feels that there is a danger of bodily harm by another person.

Answers

Assault occurs when a person feels that there is a danger of bodily harm by another person this statement is false.

When someone willfully puts another person in fear of immediate bodily harm, they have committed assault, which is a crime.

It is a form of physical aggression that includes a variety of actions, including shoving, hitting, and threatening to hurt someone. It only requires the threat of damage rather than real physical contact or injury.

In order for there to have been an attack, the victim must have a reasonable belief that the harm is about to happen, even if the threat was not followed through on. To put it another way, assault is a crime that entails inciting fear of harm rather than really doing harm.

Online estimators, metabolic carts (i.e. lab equipment), dietary recall questionnaires are all acceptable methods of estimating caloric needs

Answers

The correct one is Online estimators, metabolic carts (i.e. lab equipment), dietary recall questionnaires are all acceptable methods of estimating caloric needs.

The calorie is an energy unit derived from the now-defunct caloric theory of heat. Two primary meanings of "calorie" are widely used for historical reasons. Originally, the big calorie, meal calorie, or kilogramme calorie was defined as the amount of heat required to increase the temperature of one kilogramme of water by one degree Celsius (or one kelvin). The amount of heat required to create the same rise in one gramme of water was characterised as a tiny calorie or gramme calorie.

Most nutritionists in the United States prefer the unit kilocalorie to the unit kilojoules, although most physiologists favour kilojoules. Nutritionists in the majority of other nations prefer the kilojoule to the kilocalorie. The unit is most typically used to indicate food energy, specifically the specific energy (energy per mass) required to metabolise various forms of food.

You are the manager of a small store that specializes in hats, sunglasses, and other accessories. You are considering a sales promotion of a new line of hats and sunglasses. You will offer the sunglasses only to those who purchase two or more hats, so you will sell at least twice as many hats as pairs of sunglasses. Moreover, your supplier tells you that, due to seasonal demand, your order of sunglasses cannot exceed 100 pairs. To ensure that the sale items fill out the large display you have set aside, you estimate that you should order at least 210 items in all. Assume that you will lose $3 on every hat and $2 on every pair of sunglasses sold.
