Approximately 95% of all newborn respiratory rate are between what two values? What is the approximate probability that a randomly chosen newborn has a respiratory rate of 55 breaths per minute or more? What is the approximate probability that a randomly chosen newborn has a respiratory rate between 40 and 55 breaths per minute? 11.25 The Wechsler Adult Intelligence Scale (WAIS) is the most commonly used "IQ test." The scale of scores is set separately for each age group and is approximately Normal with mean 100 and standard deviation 15. Use the 68-95-99.7 rule to answer the following questions. a) What percent of people have WAIS scores above 100? Above 145? Below 85?

11.17-11.19 The respiratory rate (in breaths per minute) in newborns varies according to a distribution that is approximately Normal with mean 50 and standard deviation 5. (Use this information to answer the following: Approximately 95% of all newborn respiratory rate are between what two values? What is the approximate probability that a randomly chosen newborn has a respiratory rate of 55 breaths per minute or more? What is the approximate probability that a randomly chosen newborn has a respiratory rate between 40 and 55 breaths per minute? 11.25 The Wechsler Adult Intelligence Scale (WAIS) is the most commonly used "IQ test."
