What is a one sample binomial test?
The binomial test, also known as the one-sample proportion test or test of one proportion, can be used to determine whether the proportion of cases (e.g., “patients”, “potential customers”, “houses”, “coins”) in one of only two possible categories (e.g., patients at “high” or “low” risk of heart disease, potential …

How do you do a single t-test?
How to perform the one-sample t-test
- We calculate a test statistic.
- We decide on the risk we are willing to take for declaring a difference when there is not a difference.
- We find the value from the t-distribution based on our decision.
- We compare the value of our statistic (3.07) to the t value.
What is a one sample t test and when is it used?
The one-sample t-test is used when we want to know whether our sample comes from a particular population but we do not have full population information available to us. For instance, we may want to know if a particular sample of college students is similar to or different from college students in general.
What test is prop test?
The prop. test( ) command performs a two-sample test for proportions, and gives a confidence interval for the difference in proportions as part of the output. The z-test comparing two proportions is equivalent to the chi-square test of independence, and the prop.
