Use z scores to compare the given values.The tallest living man at one time had a height of 254 cm. The shortest living man at that time had a height of 110.2 cm. Heights of men at that time had a mean of 173.29 cm and a standard deviation of 8.36 cm. Which of these two men had theheight that was more extreme?Since the z score for the tallest man is z=and the z score for the shortest man is z=, theV man had the height that was more extreme.(Round to two decimal places.)

Brooklyn earned a score of 850 on Exam A that had a mean of 550 and a standard deviation of 100. She is about to take Exam B that has a mean of 650 and a standard deviation of 20. How well must Brooklyn score on Exam B in order to do equivalently well as she did on Exam A? Assume that scores on each exam are normally distributed.
A doctor in the oncology department of a hospital surveyed the breathing rateof cancer patients. The mean and standard deviation of breathing rates for a group of patients are 12 and 2.3 breaths per minute, respectively. State the theorem applied"proportion of the patients having breathing rates from 7.4 to 16.6 breaths per minute" and explain why this theorem is chosen.
The distribution of heights of adult men is approximately normal with mean 69 inches and standard deviation 2.5 inches. Bob's height has a Z-score of -2.5 when compared to all adult men. In 1-2 sentences, interpret what this Z score tells about how Bob compares to other men in terms of height.
Logan and Brian began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Logan took a test in Art History and earned a 76.8, and Brian took a test in English and earned a 68.9. Use the fact that all the students' test grades in the Art History class had a mean of 71.9 and a standard deviation of 11.6, and all the students' test grades in English had a mean of 61 and a standard deviation of 9.4 to answer the following questions.a) Calculate the z-score for Logan's test grade.z=z= [Round your answer to two decimal places.] b) Calculate the z-score for Brian's test grade.z=z= [Round your answer to two decimal places.]c) Which person did relatively better? Logan Brian They did equally well.
Willow Road and Arroyo Seco are schools in different states. The heights of students at Willow Road have a population mean of 50.4 inches and a standard deviation of 6 inches. The heights of students at Arroyo Seco have a population mean of 54.3 inches with a standard deviation of 2.3 inches. For each school, the distribution of the heights of students is clearly bell-shaped.Elsa is a student at Willow Road and is 67 inches tall. Jane is a student at Arroyo Seco and is 59 inches tall.
A pupil in grade 2 jumped 3.2 m for the long jump. The class mean is 2.5 m with a standard deviation of 0.4 m. A pupil in grade 8 at the same school jumped 4.3 m in a class with a mean of 3.4 m and a standard deviation of 0.5 m. Which student should receive the long jump medal for the school track meet?
In class A, Jamir got 85 for his first test. Jamir's class mean was 75 and the standard deviation was 5.In class B, Laurabelle got 80 in her first test. Laurabelle's class mean was 50 and the standard deviation was 10.In a fair comparison of the two students in two different classes, who did better in his or her test. (Compare Jamir and Laurabelle's standing in their classes.Note Z-score gives that information.) Jamir Laurabelle Both did the same none of the above
