I plugged the same values as you in my calculator but I got different numbers, is that fine?

[@mporinchak]

If you plugged in the exact same thing I did into the exact same command you should not get different values.

In an FRQ, would I still have to show every step of the calculation part even if I use my calculator?

[@mporinchak]

Great question. You still have to name the procedure and identify what you are doing. But you can use the calculator to get the test statistic and p value or interval

thank you!

[@mporinchak]

You're welcome!

[@reneeyankah9102]

why is 0.01 used as the value that is against the other p values?

[@mporinchak]

That is the alpha value that in most AP problems is given as 1% or 5%, but if no value is given you can pick. So I used 1%
