Census data for a certain county show that 19% of the adult residents are hispanic. suppose 74 people are called for jury duty and only 10 of them are hispanic. does this apparent underrepresentation of hispanics call into question the fairness of the jury selection system? explain.

Yes. The jury pool are, in the US constitution, demanded to be fair and have a representative amount of people from that county. That happens because people from different background have different views on cases. If, for example, the State is acusing a black person in a non-fair way, only because of the color of their skin, jury formed by black majority is more likely to see the Racism of the State in this case and judge in a place where they are not interested in arresting that person only because she/he is black, specially when that person comes from a racial segregate community that is usually already judged in a racist way.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
