🧵 Math Stats I NEED HELP
Anonymous at Mon, 4 Nov 2024 08:03:39 UTC No. 16461893
I have been trying to figure out how P-values work but I don't exactly get it
Whenever I look stuff up all I can find is the stuff using a table but we weren't taught and we can't use the table
i inputted the formula for this right-tailed problem and it was considered it incorrect
I put this equation into a graphing calculator
X^2cdf(Xo^2,E99,n)
X^2cdf(38.24,E99,12) and got 1.402837008 E-4 not the 0.0001 which is correct
This is the equation my professor gave me so what am I doing wrong here?

P values are the "probability of false alarm" (assuming Gaussian hypotheses for both H0 and H1).
It's the probability of getting the final test statistic you've gotten while H0 is the truth.

So what would I input into the equation in this scenario?

is chi squared really the right distribution to use?

What department is this class from? No way a mathematician frames a question like this. It's fucking stupid. Reads like psychology bullshit.

Supposedly Chi distribution is correct
This is legit a college intro to stats class

>1.402837008 E-4
This is 0.0001402837008, which rounds to 0.0001

I was just telling one of your fellow Homos in another tread about P-Values. Must be Stats day
