I work through examples of finding the p-value for a one-sample t test using the t table. (It's impossible to find the exact p-value using the t table. Here I illustrate how to find the appropriate interval of values in which the p-value must lie.)

![An Introduction to Hypothesis Testing
A first look at hypothesis testing.
For those that use R, below is the R code to find the binomial probability given in this video.
To find the probability that X takes on a value that is at least 28, where X has a binomial distribution with parameters n = 100 and p = 1/4:
1-pbinom(27,100,1/4)
[1] 0.2776195
To find the probability that X takes on a value that is at least 44, where X has a binomial distribution with parameters n = 100 and p = 1/4:
1-pbinom(43,100,1/4)
