For many years TV executives used the guideline that 30 percent of the audience were?
165 = 33% ABC observed, 150/30% expected 140 = 28% CBS observed, 150/30% expected 125 = 25% NBC observed, 150/30% expected (500 less 430 is 70) 70 = 14% Cable observed, 50/10% expected Chi square test for goodness of fit (between the guideline and the sample) The Null is that the guideline and observed results have no significant difference, the Alternative is that they do have a difference. (3 degrees of freedom, 4 categories -1) gives a critical value of 7.82 at .05 significance The Chi test for this data is 14.32 so the Null is rejected and the Alternative is accepted.

Does steel have a crystalline structure?
Yes steel can have multiple types of crystalline structure or "grain" structure. These structures can be changed by heating and cooling the steel in particular ways. This is not unlike how different temperatures and cooling speeds cause water to form different sizes and shapes of ice crystals, which can be readily observed in snow crystals. In steel, the properties of the alloy will be determined in large part by the crystal structure, like hardness, ductility, tensile strength. The manipulation of these crystalline structure through controlled heating and cooling is known as tempering, or heat treating.
What structure can be observed that identifies a sample as a mineral?
Minerals are crystalline in structure. If you're looking at a solid object of inorganic origin, that occurs naturally, and it has crystals, the crystals are minerals.
What is The percent difference between an observed value and its actual value?
It is the observed error.
What is a precipitate and when is it observed?
an insoluble sold formed in a chemical reaction that is taking place on a solution. Observed when the amount (concentration) of that substance is greater than its solubility. small crystals settel out in the container.
Are isotopes different in terms of their chemical properties?
A difference of chemical properties is observed for light elements; for other elements these differences are extremely small.
