Several factors influence the value obtained for a t statistic. Some factors affect the numerator of the t statistic and others influence the size of the estimated standard error in the denominator. For each of the following, indicate whether the factor influences the numerator of dominator of the t statistic and determine whether the effect would be to increase the value of t (farther from zero) or decrease the value of t (closer to zero). In each case, assume that all other factors remain constant.
a. Increase the variability of the scores.
b. Increase the number of scores in the sample.
Increase the difference between the sample mean and the population mean.

Do conversion factors always sometimes or never have a numerator and denominator?
They always have a numerator but, if they are integers, the may not have a denominator.
How can you tell whether a fraction is in simplest form?
If the GCF of the numerator and the denominator is 1, the fraction is in its simplest form.
How is raising a quotient to a power similar to raising a product to a power?
You are both raising the factors or numerator and denominator
How do you reduce proper fractions to lowest terms?
You look for common factors, and divide both numerator and denominator by the same factor. For example, 9/12 has the common factor 3, if you divide numerator and denominator by 3, you get 3/4.
How does knowing factors help you simplify fractions?
Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.
Do conversion factors always sometimes or never have a numerator and denominator?
They always have a numerator but, if they are integers, the may not have a denominator.
How can you simplify 130 over 400?
You look for common factors in the numerator and the denominator, then divide both the numerator and the denominator by that common factor.
What is factors to the numerator and denominator?
The numerator and denominator of fractions are just whole numbers and have factors like any other number. Factor them as you would any regular whole number.
If a fraction's numerator and denominator have no factors other than one in common can the fraction be simplified?
If a fraction's numerator and denominator have no factors other than one in common, the fraction cannot be simplified except if the denominator is 1, in which case the fraction can be simplified to the whole number of the numerator.
How do you figure simplest forms of fractions?
If the numerator and denominator of a fraction have a common factor (except for '1'), divide both numerator and denominator by their common factor. The fraction is in the simplest form when the numerator and denominator have no common factors.
How can a fraction be simplified if the numerator and denominator have no factors other than one?
If the numerator and the denominator have no common factors other than one, the fraction is already in its simplest form.
What is a fraction that has no common factors in the numerator or the denominator?
If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).
What is the definition of reduced fraction?
Where the numerator and denominator have no further common factors
What are the common factors of the numerator 6 and denominator 8?
1 and 2
What is 3 over 35 in simplest form?
3/35 is the simplest form. Why? Numerator factors: 3. Denominator factors: 5 and 7. None of the numerator and denominator factors are the same and therefore cannot cancel each other out.
When multiplying use fraction notification we form products in the numerator and the denominator but do not immediatily calculate the product?
That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.
What is 18 over 56 in simple form?
Fractions can be simplified when the numerator and denominator have a common factor in them. If both the numerator and denominator have common factors, then we can cancel these factors out. So the simplest for of 18/56 is 9/28.
