An example of a false negative is taking an HIV test and having the test come back negative to say the patient is clean, but in reality they have HIV. Another example of a false negative is a woman taking a pregnancy test saying "not pregnant" (i.e. test is negative), but she actually is pregnant. Between those two examples, it is better to have a false negative pregnancy test because it is non life threatening.
A false positive example would be getting bad news you have cancer, when you actually don't have cancer. Another false positive example is a test saying you have a cold virus, when in actuality you don't. The first example mentioned would have the patient likely go through intense chemo treatments which would greatly affect their livelihood. The second example is a more harmless false positive as it would involve at most a flu shot if anything.
Answer:
The observation that could be made in regards a neon light placed in one evacuated (airless) chambea r, and battery powered radio placed in a second evacuated chamber, switched on at the same time by remote control, is that they are managed as capacitors.
Explanation:
Capacitors, also known as condensers, store energy and, we can also see them in the sky, they are the clouds.
Capacitors are made of two electrical conductors, separated by an insulator, when you add electrical energy to a capacitor you are charging a capacitor, the opposite is known as discharging.
The equation for the chi squared value is the (observed-expected)^2/E
