Hospital floors are usually covered by bare tiles. carpets would cut down on noise but might be more likely to harbor germs. to study this possibility, investigators randomly assigned 8 of 16 available hospital rooms to have carpet installed. the others were left bare. later, air from each room was pumped over a dish of agar. the dish was incubated for a fixed period, and the number of bacteria colonies were counted. the response in this study is:

Given the details of the study carried out on Hospitals to study the possibility that carpers might be more likely to harbor germs, in which air from rooms with carpet and those without carpet was pumped over a dish of agar, and the number of bacteria colonies were counted after incubating the dish for a fixed period of time. The response in this study is number of bacteria colonies in a dish.

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
