Testing a claim about a population mean: TInterval (Guided lab)

For this procedure, we will use a 80% level of confidence.

a)  Describe this context (what are you testing?) State the parameter of interest.

b) Gather your data. Enter your data here with each value separated by a comma.


b)  Are the necessary conditions present to carry out this inference procedure? Explain in context.

c)  Carry out the procedure ("crunch the numbers"):

Sample mean:

Standard error of sample mean:

Critical value: 

Margin of error: 

Confidence Interval:  (,)

Write a conclusion in context.

Now that you are done, try running STAT->TESTS->TInterval on your calculator!
