So we are going to be examined. The heights of female students on the average of 64.4 m. And the standard deviation is 2.4 m. Just kidding. It's interest. Now, the C score is looking at x minus mu divided by sigma, and that's what we're doing to find. The first boundary of X. Z is 62. So we get approximately -1. Now, for the Z score of 63, We're just gonna replace the 62-63. Okay, But unfortunately I have to write this out again and it's lot to write out sometimes, but on a test you're gonna want to do that. And the difference that we find here Or a result is going to be -058. So what this tells us is that it is between Almost 1/2 and a whole standard deviation below the mean. And now to find out what the percentages are, we're just going to look in the back of the book here. Okay. Yeah. This one is going to be point oops, mm. Bad trying, bad trying. Okay, there we go. Now. We're back in order. This one is going to be 0.15 87 Yeah. And this other one is going to be a 15%,, A much higher. 0.281. So this is going to be our ends. Okay, looking at between here and here And what we have is between 10 And 28%. To find this difference right here, It's going to be point too late. one -1587. And this difference comes out to be 12.23%. Yeah. Oh, Finally we're asked to final percentage of female students with fights between 65 and 70 in so once again will be calculating see scores. Yeah. and I wont show that math. This time, it's just 65. It's going to be at 0.25 and for 75 are sorry 70 R. Z score turns out to be a whopping 2.33 For this one. Right here we get a percentage of the 99%ile .9901. And for this one you get 0.5871 Her 5987. I was looking at the wrong role. Yeah. Richard Zoom in or whatever. Trace your finger down just so you can get the right percentage. The percentage of female students are between these two heights is going to be the difference. The difference between these two is 0.3914 Or 39.14%. Okay.
