Diastolic Blood Pressure of Females For the diastolic blood pressure measurements of females listed in Data Set 1 “Body Data” in Appendix B, the highest measurement is 98 mm Hg. The 147 diastolic blood pressure measurements of females have a mean of x =70.2 mm Hg and a standard deviation of s =11.2 mm Hg.a. What is the difference between the highest diastolic blood pressure and the mean of the dia-stolic blood pressures for females?b. How many standard deviations is that [the difference found in part (a)]?c. Convert the highest diastolic blood pressure to a z score.

Video Transcript

this lesson in this lesson, we have the highest black pressure as 98 millimeter Mirth Queen with a mean of 70.2 millimeter macro. In a standard division of 11.2 millimeter. Magritte The first part we are having the difference of the highest and the mean. So this one is X- The mean, which is recalled to 98 minus 70.2. So that is 27.8. So the difference is 27.8. The second power we are looking at how many send their divisions. Is this? And that is the difference all about the standard deviation? What is called the Z school? The so this is 27 point eight There's a difference minus 70 Point to All of the Standard Deviation? Yes, 27.8. All over 11.2 And this is two for eight. Okay, okay, so this is how many standard deviations is it from the highest for the mean is from the highest point, The highest point is from the media. Now the Cpac, we're converting this to Aziz call. So disease called is equal to the value minus the me All over the standard. Waiting just as we've we've done. So this has a disease call of 98.7. They're all point to 98 -7. 0.2. All over 11.2. So well we actually calculated it's disease call. How many standard divisions? It is from there mean, is there's the school. All right. Since the time. This is the end of the lesson
