studied common breath metabolites such as ammonia, acetone, isoprene, ethanol, and acetaldehyde in five subjects over a period of 30 days. Each day, breath samples were taken and analyzed in the early morning on arrival at the laboratory. For subject A, a 27-year-old female, the ammonia concentration in parts per billion (ppb)followed a normal distribution over 30 days with a mean of 491 and a standard deviation of 119. (a) What is the probability that on a random day, the subject’s ammonia concentration is between 292 and 649 ppb? Explain your step by step computation

Question
Diskin et al. (A-11) studied common breath metabolites such as ammonia, acetone, isoprene, ethanol, and acetaldehyde in five subjects over a period of 30 days. Each day, breath samples were taken and analyzed in the early morning on arrival at the laboratory. For subject A, a 27-year-old female, the ammonia concentration in parts per billion (ppb)followed a normal distribution over 30 days with a mean of 491 and a standard deviation of 119.
