You wish to test the following claim (HaHa) at a significance
level of α=0.10α=0.10.
Ho:μ1=μ2Ho:μ1=μ2
Ha:μ1<μ2Ha:μ1<μ2
You obtain the following two samples of data.

What is the test statistic for this sample? (Report answer accurate
to three decimal places.)
test statistic =
What is the p-value for this sample? For this calculation, use the
degrees of freedom reported from the technology you are using.
(Report answer accurate to four decimal places.)
p-value =
The p-value is...
This test statistic leads to a decision to...
As such, the final conclusion is that...
If you could please show me how to do this answer on a TI84 PLUS as well please
both of the data samples it wants both samples t statistic and whatnot i don't know how to post a photo but this is copied and pasted
sample #1 | sample #2 | ||
x1 = | 50.082 | x2 = | 58.419 |
s1 = | 12.507 | s2 = | 8.663 |
n1 = | 51.000 | n2 = | 48.000 |
standard error se=√(S21/n1+S22/n2)= | 2.1519 | ||
test stat t =(x1-x2-Δo)/Se= | -3.874 |
p value : = | 0.0001 |
The p-value is. less than alpha
The sample data support the claim that the first population mean is less than the second population mean.
(if you want from ti-84: press stat-edit: put values in L1,L2 register
then again press stat- tests --0:2-SampTInt )
