Okay. And all hypothesis, population standard deviations are the same alternative, is that they are not the same or different, does not equal. We're conducting this experiment at a 1% significance law And f is going to be 74.8 squared. Yeah, Divided by 30.4 Squared. This is approximately equal to 6054. Our degrees of freedom are going to be six and eight. Yeah. Mhm. Okay. Since his point all one Half of that is going to be .05, So f. 05. Since it's the two tail test Is going to be 7.9. What just happened there? 7.95. Now, f of 1 -15 or point 995 is equal to one over 10.57. You can find these values in Table gate. Keep in mind that this value right here was found by reversing these values right here in table bait, 1/10 57 is equal to 0.09. Yeah. Alright. Now that we've got all these numbers here, we can compare these two numbers there. So for two tailed tests, we got two tails as the name says, Okay, I don't really know how to draw this, but let's just go with this shark fin looking thing. So we have 7.95. So that's going to be right here. Mhm. Yeah. So that's gonna be the 7.95. We'll just call that eight And the other one is your .09. It's gonna be over here. We'll call that zero. And then we got six which is smack dab in the middle. Therefore At the 10 Sorry, significance level. We failed to reject the null hypothesis. Whoops. Can't do that. There we go. Now. For the beautiful part that I like the confidence and rules. Here they are. Mhm. I believe we figured out our values from last time 7.95 and 0.09. So all we have to do is plug 7.95 in right here, 10 0.09 Right There. And the corresponding standard deviations For the lower bound will get 0.873 For the upper bound will get 8.202. Therefore our 99% confidence interval is 0.873 two, 8.202.
