The z value for a 99.5% confidence interval estimation is

Biology
1 answer:
kompoz [17]3 years ago
3 0

Answer & explanation:

A confidence interval is an estimated range of a parameter of interest. Confidence intervals are used to indicate the reliability of an estimate. For example, a confidence interval can be used to describe how reliable a search result is.  

In other words, a high confidence interval Z value implies that a survey is more likely to indicate the actual values being presented.

In biostatistics, for example, the Z value can be used in calculations to assess the prevalence of a particular disease and the factors associated with it in a population.

The value of Z, however, is not used as a percentage (like the 99.5% addressed in this question) for calculations. A universal table is used to convert Z values and use them in statistical calculations.

Some examples of Z value conversions can be found in the table attached in this question.

Which information is needed to construct a geomagnetic time scale?
AleksAgata [21]

Answer:

the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth

Explanation:

The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.

During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.

To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.

Answer:

1.The pleural cavity aids optimal functioning of the lugs during breathing. It transmits movements of the chest wall to the lungs, particularly during heavy breathing. The closely approved chest wall transmits pressures to the visceral pleural surface and hence to the lung (10-19.

2.The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarge.

Steve, a 32-year-old man, suffers from liver damage. Clinical examination reveals that it was caused by a toxin produced by a ce
Ymorist [56]

Answer: Aspergillus

Explanation:

Aspergillus is the fungal species which is highly aerobic in nature. It is found in the oxygen rich environment. This fungal species grows as molds typically over the substrate, as a result of high oxygen tension. The molds are toxic in nature. It grows over certain fruits, vegetables like apricots, peanuts, onions and grapes. It is the common contaminant of food. It is responsible for causing liver cirrhosis.

On the basis of the given situation this can be said that Steve is infected by Aspergillus.
