I'm not sure what each symbol means when trying to do a ttest.

TTest: [Stat] > Tests > 2:TTest. You may input your data into L1 first.
The first line, involving μ, is the alternative hypothesis.
t is the test statistic, the standardized difference between the sample mean and μ0. If the null hypothesis is true, it should be close to 0.
p is the probability that the difference between the sample mean and μ0 would occur if the null hypothesis is true. When the value is sufficiently small, we reject the null hypothesis and conclude that the alternative hypothesis is true. You should have a cutoff value ready, such as 5% or 1%. If p is lower, you "reject the null hypothesis on a 5% (or 1%) level" in technical terms.
xbar is the sample mean.
Sx is the sample standard deviation.
n is the sample size (not included, but also important, is df, the degrees of freedom, defined as n1)

go to
Stat>TESTS> 2. TTest
and then you can either put the data in list 1 and calculate it, or choose "stats" and type in the information
the U looking thing (mew) with sub zero is the null hypothesis and at the bottom the not equal to is if your testing that your alternate is not equal to the null, the < is whether the null hypothesis is greater than and > is whether you are testing if it is less than
under stat>TESTS there are also 2sample ttests and tinterval if you need it.Source(s):
i am doing this in math right now.
