Define Phat in statistics?
p-hat is the 'proportion in your sample.' It may be given as a percentage, a proportion or you will have to figure it out as a fraction (proportion).
What is a proportion of 100?
Percent or percentage
Is a proportion an example of a continuous variable?
No
What is the purpose of the sample proportion?
The sampling proportion may be used to scale up the results from a sample to that of the population. It is also used for designing stratified sampling.
A sample of 66 observations will be taken an infinite population The population proportion equals 0.12 The probability that the sample proportion will be less than 0.1768 is?
.9222
What is the direct proportion formula?
x and y are in direct proportion if there is some positive constant c such that y = cx
Why rubber have the same empirical formula as its monomer?
An empirical formula only takes into account the proportions of the elements in a compound. The proportion of elements in a polymer might be the same or similar as the proportion in the monomer from which it is made.
The simplest possible formula that illustrates the proportion of elements in monosaccharides is what?
The simplest formula to illustrate the proportion of elements in monosaccharides is CH2O, since monosaccharides have the general formula (CH2O)n, where n is typically between 3 and 7.
What does a better job at representing the proportion of the area under the standard curve?
the formula
What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.
How law of constant proportion applied in experiment empirical formula of a compound?
percentage of mg
What is the name of two or more elements in a fixed proportion?
A compound refers to two or more elements chemically bonded together in a fixed proportion. This fixed proportion is represented by a chemical formula that shows the types and ratios of atoms present in the compound.
What is the formula for a proportion?
1.What is the formula for a proportionp = n / f2. p = (f / 100) * n3. p = f / n4. p = (f / n) * 100
How is the Law of definite composition and proportion relate to the empirical formula?
The Law of Definite Composition states that a compound will always have the same proportion of elements by mass. This relates to the empirical formula because the empirical formula gives the simplest whole number ratio of the elements in a compound, which reflects the fixed composition of elements as per the Law of Definite Composition.
How law of constant proportion is applied in experiment empirical formula of magnesium oxide?
The law of constant proportion states that a chemical compound always contains its constituent elements in fixed ratio by mass. In the experiment to determine the empirical formula of magnesium oxide, magnesium is burned in oxygen, resulting in magnesium oxide. By measuring the mass of magnesium and the mass of oxygen reacted, the ratio of these two elements can be calculated. This ratio reflects the law of constant proportion, allowing the empirical formula of magnesium oxide to be determined, typically represented as MgO.
What are the 4 types of proportion?
direct proportion indirect proportion additive proportion partitive proportion
What is a statement of equality between two ratios called?
... a proportion.... a proportion.... a proportion.... a proportion.
