How can you find the grade average from 20 wrong out of 75 questions?
If you got 20 problems wrong on a 75 question test your grade would be 73% or a C. You can find that by subtracting the amount of questions you got wrong from the amount you got right, 55 in this case. Divide the amount of correct questions by the amount of questions on the test to get .733333. That is the grade.

How do you find the degrees of freedom when using the t distribution to estimate or test the mean of a sample from a single population?
If the sample consisted of n observations, then the degrees of freedom is (n-1).

Why is it impossible to compute a T statistic for a sample that has only one score?
A T test is used to find the probability of a scenario given a specific average and the number of degrees of freedom. You are free to use as few degrees of freedom as you wish, but you must have at least 1 degree of freedom. The formula to find the degrees of freedom is "n-1" or the population sample size minus 1. The minus 1 is because of the fact that the first n is not a degree of freedom because it is not an independent data source from the original, as it is the original. Degrees of freedom are another way of saying, "Additional data sources after the first". A T test requires there be at least 1 degree of freedom, so there is no variability to test for.
How do you use the F Test to find the sample size for two sets of data?
The data sets determine the degrees of freedom for the F-test, nit the other way around!

How do you work out degrees of freedom?
Degrees of freedom (df) refer to the number of independent values or quantities that can vary in a statistical analysis. In general, for a sample, the degrees of freedom can be calculated as the sample size minus one (df = n - 1) when estimating a population parameter, like the mean. For other statistical tests, such as t-tests or ANOVA, the degrees of freedom depend on the number of groups and sample sizes involved, following specific formulas outlined for each test.
Find the critical value for c0.99 and n10?
To find the critical value ( c_{0.99} ) for a sample size of ( n = 10 ) in a t-distribution, you first identify the degrees of freedom, which is ( n - 1 = 9 ). Using a t-table or calculator, you look up the critical value for a one-tailed test at the 0.99 significance level with 9 degrees of freedom. The critical value ( c_{0.99} ) is approximately 2.821.
What information do you need to locate the critical value for a t test?
To locate the critical value for a t-test, you need the significance level (alpha, typically 0.05 for a 95% confidence level) and the degrees of freedom, which are calculated based on the sample size (n). For a one-sample t-test, degrees of freedom are usually n - 1. For two-sample t-tests, you may need to consider the sizes of both samples. With this information, you can refer to a t-distribution table or use statistical software to find the critical t value.
What is the degrees of freedom for 95 percent?
Degrees of freedom (df) typically refers to the number of independent values or quantities that can vary in a statistical analysis. In the context of a 95% confidence level, degrees of freedom are often associated with sample size in t-tests or ANOVA. For instance, in a t-test, df is calculated as the sample size minus one (n - 1). Thus, to determine the specific degrees of freedom for a 95% confidence interval, you would need to know the sample size involved in your analysis.
What is the critical value of chi-square with a significant level of equals 0.05?
Critical values of a chi-square test depend on the degrees of freedom.
