Going? Ah, start to school. Problem number 61. Ah, we know from the given that, um that meaning mean. Oh, Max. Ah, Liquid won't win before. And standard deviation X, It was no point Open three. This is from the givens. Okay. We also know that on the property for, ah, property for the mean and some of the feeling that mean off and a x A plus b ah, why and equals a and looking blowing boy mean off of experts Be withdrawing by green Old Reich and also on rebellions. Rebellions on OPEC's Except be wind equal e square. Ah, look! The growing boy Variance. Ah x radiance of X Cross me. It's weird. Ah, not growing, boy radiance. Oh, what? These are a properties were I mean and and very insult. Okay, so now we are trying to find the mean off ah of X. We're tryingto find mean off x one, minus Exton and minus x tuned. And this is equal to Yeah. Oh, x one A minus me. And, well, ex cool, Which is equally true? One point for us. One point for 8 to 0. Ah, And for the Sunday the radiation from the baby. Oh, x one minus x two. And this is equally as we know that snuck me in is a square root that's brutal off the Iranians. 20 minutes extreme on and from using this property we can say that Ah, the variance is equal to ah ah equipped to variants of X both variance. All right, record low coefficient a and be in this case is equipped one ah two. And this can be equally square Root off Uh oh Quin Cree school which is the standard deviation stated in the in the evening Plus opened a three s quit and so the front answer would be negative. Naturally will be no point for 143 So this is a mean off X 1162 And this is the Sun division off X one minus x two. Okay, so now we are trying to find a problem. Anything trying for Fine. Um, this is a family. Okay, so now we're front performances it brandy, which is which means of ending. Uh then you minus mean and you wanted me over standard babies. Okay. And we also complete this. Ah, it's venues. Ah, So, uh, we work returning that we find the value off. It's smaller than 1.1. So one point corn hands of some of the Venusian use. Uh huh. Does it is. The square is a very decreased body. They need the world wasn't deviation. So it's 1.1 minus 1.8. This is the value we are trying to find. When a zero, which is in me over the Central Division, she is opened 4 to 443 Yeah. What is it ready for multiples? Didn't really is equal to negative at one point, it might. Now we are trying to find the probability. Um, we're trying to find the probability. Ah, that and then Ah, smaller, thin negative. At one point, it it my ah, or the probability that's is it. And it's bigger than one point 1.8 eight. No. Okay, we're trying to find these probabilities and actually her for that. The smaller than, ah, negative 1.9. If this is a distribution, um, did smaller than 1.9, So we're tryingto find and it's probability. And is it the bigger than 1.89? So we are trying to find this area under the care and these two areas are the same. So we can say that probably it was that this more than negative 1.8 or parole it was that bigger than 1.89 And they are and the same. So it's equal to two month blind by, um Ah, probability. Huh? Hasn't, um, smaller than negative 1.8 on 28 9 Okay. Promoting the the tables to find the value for this probability s o from the table. Ah, we found that the probability for the area under the curve for 20 this'll area in equal tune. Good point. Uh oh. Two, nine four. It was a final answer for that is equal to So it's when the answer was that they worked. Ah, all points. Whole point. Mmm. Why? Eight. Eight. Thank you.
